A microsecond is an SI unit of time equal to one millionth (10⁻⁶ or ¹/_1,000,000) of a second. Its symbol is µs.

A microsecond is equal to 1000 nanoseconds or ¹/_1,000 millisecond. Because the next SI unit is 1000 times larger, measurements of 10⁻⁵ and 10⁻⁴ seconds are typically expressed as tens or hundreds of microseconds.

Examples[link]

• 1 microsecond (1 μs) – cycle time for frequency 1 x 10⁶ hertz (1 MHz), the inverse unit. This corresponds to radio wavelength 300 m (AM mediumwave band), as can be calculated by multiplying 1 µs by the speed of light (approximately 3×10⁸ m/s) to determine the distance travelled.
• 1 microsecond – the length of time of a high-speed, commercial strobe light flash.
• 1.8 microseconds - the amount of time subtracted from the Earth's day as a result of the 2011 Japanese earthquake.
• 2 microseconds – the lifetime of a muonium particle
• 2.68 microseconds – the amount of time subtracted from the Earth's day as a result of the 2004 Indian Ocean earthquake.^[1]
• 3.33564095 microseconds – the time taken by light to travel one kilometer in a vacuum
• 4.63 microseconds – a fifth (a 60th of a 60th of a 60th of a second)
• 5.4 microseconds – the time taken by light to travel one mile in a vacuum
• 10 microseconds (μs) – cycle time for frequency 100 kHz, radio wavelength 3 km
• 17 microseconds: net amount per year that the length of the day lengthens, largely due to tidal acceleration.^{[citation needed]}
• 20.8 microseconds – sampling interval for digital audio with 48000 samples/s
• 22.7 microseconds – sampling interval for CD audio (44100 samples/s)
• 38 microseconds – discrepancy in GPS satellite time per day (compensated by clock speed) due to relativity^[2]
• 50 microseconds – cycle time for highest human-audible tone (20 kHz)
• 100 microseconds (0.1 ms) – cycle time for frequency 10 kHz
• 125 microseconds – sampling interval for telephone audio (8000 samples/s)
• 240 microseconds – half-life of copernicium-277
• 250 microseconds – cycle time for highest tone in telephone audio (4 kHz)^{[citation needed]}
• 277.8 microseconds - a fourth (a 60th of a 60th of a second), used in astronomical calculations by al-Biruni and Roger Bacon in 1000 and 1267 AD, respectively.^[3][4]

Katerina Moutsatsou (also spelled Moutsatsos; Greek: Κατερίνα Μουτσάτσου), is a Greek actress.

Biography[link]

The daughter of a Greek naval officer, Moutsatsou was born September 21, 1972 in Monterey, California while her father was on foreign duty in California, yet grew up almost exclusively in Greece. She studied in Paris and graduated from Paris III - Sorbonne University. She holds a Maitrise in Theater Arts And Acting and a D.E.A (the equivalent of a Masters degree) in Theater Arts.

Moutsatsou is also a professional dancer. After 10 years of classical ballet education in Athens (Royal Academy Of Dancing System – “Advanced” level), she joined choreographer Mia Frye's classes at the “Centre de Danse du Marais” in Paris for five years. In the beginning of her acting career, Moutsatsou taught hip hop in Greece and choreographed videoclips for the boy-band 4-Play. Katerina has also worked briefly as a singer and has supported major Greek singers such as Anna Vissi and Sakis Rouvas. Her duet "Mia Fora" with composer and singer Dimitris Korgialas in 2004 was a huge hit and won two awards at the 2004 Mad Music Awards as the best duet and best rock song.

Moutsatsou has shared her life between Athens and Istanbul since 1998. She has become a popular figure for the Turkish public, appearing on the cover of more than 30 magazines in Greece and Turkey. She has had a regular role since the second season of Yabancı Damat.

Moutsatsou performed the role of Evdokia Iordanidou in the film Kayıkçı released on 24 September 1999.^[1]

She also took part in the series called Tutkunum Sana in 2006 in Turkey.

In 2008, she left Turkey to for a 'new challenge' pursuing acting in Los Angeles. She had a bit part in the smash-hit The Hangover, and co-stars as one of three friends trying to get rid of a corpse in the indie production Kill the Habit due for release in 2011.

In 2011, Moutsatsou wrote, directed and produced the short film "Loverly", starring Andy Gillet.

She is fluent in six languages: her native Greek, as well as Turkish, German, Italian, French, and English.
