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).
Unit may refer to:
A video lesson or lecture is a video which presents educational material for a topic which is to be learned. Such videos might then be loaded onto the Internet for use as online lectures.
The format may vary. It might be a video of a teacher speaking to the camera, photographs and text about the topic or some mixture of these. The Khan Academy has been successful in teaching mathematics using notes written using Yahoo!'s doodle pad with a voiceover by Salman Khan (educator). These were then loaded onto YouTube where they have been popular and influential. Such lectures are a key part of flip teaching in which the initial work of communicating the essentials of the topic is done by the video lesson.
Unit and Measurements for IIT-JEE Physics | CBSE Class 11 XI | Video Lecture in Hindi Measurement is the assignment of a number to a characteristic of an object or event, which can be compared with other objects or events.[1][2] The scope and application of a measurement is dependent on the context and discipline. In the natural sciences and engineering, measurements do not apply to nominal properties of objects or events, which is consistent with the guidelines of the International vocabulary of metrology published by the International Bureau of Weights and Measures. However, in other fields such as statistics as well as the social and behavioral sciences, measurements can have multiple levels, which would include nominal, ordinal, interval, and ratio scales In this chapter you will stu...

This lesson consists of providing you with a Self-Tutorial of the basic units used in measurement. These are the ones I discuss: Units of Time, Units of Length (Metric and U.S.), Units of Area (Metric and U.S.), Units of Volume (Metric and U.S.), Units of Mass (Metric and U.S.), Units of Liquid Capacity (Metric and U.S.), Units of Dry Capacity (Metric and U.S.), and other miscellaneous Units. Conversion Formulas and Abbreviations are also listed. This is a "must have" Lesson for those moving on to solving Word Problems in Algebra and other higher math.
From the ProEdify TEAS V prep course, this is part 1 of the lesson on units of measure. In this introduction to scientific measurements and the SI system, we discuss the scientific definition of a measurement, important SI units of measure and we break down the difference between base and derived quantities. -- Table of Contents: What is a unit of measure? - 1:12 Important base properties for TEAS V - 1:50 Base quantities vs Derived Quantities - 2:17 Explanation of unit names in SI system - 3:29 Sources Used in this Video 1) Physics 9th Edition Cutnell, John D., and Kenneth W.

Suppose I measure a stick with my fingers such the stick is 10 fingers long then here finger is the unit but its non standard. Meter is the standard unit of Length as If we measure same stick in meters then it might be as 1 meter long.
