Units of measurement
A unit of measurement is a definite magnitude of a physical quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same physical quantity. Any other value of the physical quantity can be expressed as a simple multiple of the unit of measurement.
For example, length is a physical quantity. The metre is a unit of length that represents a definite predetermined length. When we say 10 metres (or 10 m), we actually mean 10 times the definite predetermined length called "metre".
The definition, agreement, and practical use of units of measurement have played a crucial role in human endeavour from early ages up to this day. Different systems of units used to be very common. Now there is a global standard, the International System of Units (SI), the modern form of the metric system.
In trade, weights and measures is often a subject of governmental regulation, to ensure fairness and transparency. The International Bureau of Weights and Measures (BIPM) is tasked with ensuring worldwide uniformity of measurements and their traceability to the International System of Units (SI).

Biblical and Talmudic units of measurement
Biblical and Talmudic units of measurement were used primarily by ancient Israelites and appear frequently within the Hebrew Bible as well as in later Judaic scripture, such as the Mishnah and Talmud. These units of measurement are still an important part of Jewish life today. There is much debate within Judaism, as well as by outside scholars, about the exact relationship between measurements in the system and those in other measurement systems, such as the English units system used in the United States of America. Classical statements, such as that an Etzba was seven barleycorns laid side by side, or that a Log was equal to six medium-sized eggs, are so indefinite and vague as to be nearly useless. Nevertheless, the entire system of measurement corresponds almost exactly with the Babylonian system, and in all probability the Israelite measurement system was derived from the Babylonian, with some lesser level of influence from the Egyptian system. It may therefore be assumed that the relationship between the Israelite measurements and contemporary units is the same as the relationship between the Babylonian system and contemporary units.

WSKG is here to help you help your child understand the basic concepts of the common core curriculum with our Good To Know video series!
This video addresses Common Core Grade 4 Standard Measurement & Data: Solve problems involving measurement and conversion of measurements from a larger unit to a smaller unit. Know relative sizes of measurement units within one system of units including km, m, cm; kg, g; lb, oz.; L, mL; hr, min, sec. Within a single system of measurement, express measurements in a larger unit in terms of a smaller unit. Record measurement equivalents in a two-column table.
VIDEO SCRIPT: Units of Measure
In fourth grade, your child will use the metric system to measure length, mass, and capacity. Length refers to the measurement of something from end to end. Long lengths are called distance.
Mass refers to the measure of the amount of matter in an object.
Capacity refers to the maximum amount that something can contain, commonly called volume. This cup has a maximum capacity that is much smaller than the capacity of this swimming pool.
Kilometer, meter, and centimeter are metric measurements of length. Kilogram and gram are used to measure mass. Liter and milliliter measure capacity.
Learning what unit is appropriate for each measurement can be challenging. Ask your child:
What unit is best to measure our trip to grandma’s house? Is it best to measure your mass in kilograms or grams? What unit is used to tell us the capacity of this juice bottle?
Talk about these units at home so your child will be confident when converting units of measure. That is, expressing a measurement in a different unit. He will recognize patterns of converting units on the place value chart. Just as one-thousand grams is equal to one kilogram, one-thousand ones is equal to one thousand.
Your child will practice this by completing conversion charts. He will convert between units using his place value knowledge. Talking about length, mass, and capacity will help your child become familiar and confident with all types of units!
Knowing which unit is larger or smaller is important as he converts from one unit to another unit within a system of measurement. Having a strong understanding of units is very helpful when your child begins to add, subtract, multiply, and divide with units of measure.
And that’s good to know.
Note: Pounds, ounces, and time are explored but not tested in Grade 4.

All the physical quantities are given by a few fundamental quantities or their combinations. The units of such fundamental quantities are called base units, combinations of them being called derived units. The system in which length, mass and time is adopted as the basic quantities, and from which the units of other quantities are derived, is called the absolute system of units.In the SI system of units the first three fundamental dimensions are mass, length and time. The units used to measure these dimensions (and their abbreviations) are defined to be the kilogram (kg), the meter (m) and the second (s).Dimensional analysis is the analysis of the relationships between different physical quantities by identifying their base quantities (such as length, mass, time, and electric charge) and units of measure.All instruments have a smallest increment that can be detected. This smallest increment is called the least- count of the instrument. A meter stick has markings every millimeter (0.001 meter) so its least-count is 0.001 meter. In this video we will cover:-

WSKG is here to help you help your child understand the basic concepts of the common core curriculum with our Good To Know video series!
This video addresses Common Core Grade 4 Standard Measurement & Data: Solve problems involving measurement and conversion of measurements from a larger unit to a smaller unit. Know relative sizes of measurement units within one system of units including km, m, cm; kg, g; lb, oz.; L, mL; hr, min, sec. Within a single system of measurement, express measurements in a larger unit in terms of a smaller unit. Record measurement equivalents in a two-column table.
VIDEO SCRIPT: Units of Measure
In fourth grade, your child will use the metric system to measure length, mass, and capacity. Length refers to the measurement of something from end to end. Long lengths are called distance.
Mass refers to the measure of the amount of matter in an object.
Capacity refers to the maximum amount that something can contain, commonly called volume. This cup has a maximum capacity that is much smaller than the capacity of this swimming pool.
Kilometer, meter, and centimeter are metric measurements of length. Kilogram and gram are used to measure mass. Liter and milliliter measure capacity.
Learning what unit is appropriate for each measurement can be challenging. Ask your child:
What unit is best to measure our trip to grandma’s house? Is it best to measure your mass in kilograms or grams? What unit is used to tell us the capacity of this juice bottle?
Talk about these units at home so your child will be confident when converting units of measure. That is, expressing a measurement in a different unit. He will recognize patterns of converting units on the place value chart. Just as one-thousand grams is equal to one kilogram, one-thousand ones is equal to one thousand.
Your child will practice this by completing conversion charts. He will convert between units using his place value knowledge. Talking about length, mass, and capacity will help your child become familiar and confident with all types of units!
Knowing which unit is larger or smaller is important as he converts from one unit to another unit within a system of measurement. Having a strong understanding of units is very helpful when your child begins to add, subtract, multiply, and divide with units of measure.
And that’s good to know.
Note: Pounds, ounces, and time are explored but not tested in Grade 4.

All the physical quantities are given by a few fundamental quantities or their combinations. The units of such fundamental quantities are called base units, combinations of them being called derived units. The system in which length, mass and time is adopted as the basic quantities, and from which the units of other quantities are derived, is called the absolute system of units.In the SI system of units the first three fundamental dimensions are mass, length and time. The units used to measure these dimensions (and their abbreviations) are defined to be the kilogram (kg), the meter (m) and the second (s).Dimensional analysis is the analysis of the relationships between different physical quantities by identifying their base quantities (such as length, mass, time, and electric charge) and units of measure.All instruments have a smallest increment that can be detected. This smallest increment is called the least- count of the instrument. A meter stick has markings every millimeter (0.001 meter) so its least-count is 0.001 meter. In this video we will cover:-
1.Introduction to physical and non-physical quantities.
2.What are Base units?
3.What are derived units?
4.What do we mean by SI units?
5.How many base units are there?

Units of measurement
A unit of measurement is a definite magnitude of a physical quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same physical quantity. Any other value of the physical quantity can be expressed as a simple multiple of the unit of measurement.
For example, length is a physical quantity. The metre is a unit of length that represents a definite predetermined length. When we say 10 metres (or 10 m), we actually mean 10 times the definite predetermined length called "metre".
The definition, agreement, and practical use of units of measurement have played a crucial role in human endeavour from early ages up to this day. Different systems of units used to be very common. Now there is a global standard, the International System of Units (SI), the modern form of the metric system.
In trade, weights and measures is often a subject of governmental regulation, to ensure fairness and transparency. The International Bureau of Weights and Measures (BIPM) is tasked with ensuring worldwide uniformity of measurements and their traceability to the International System of Units (SI).
