Cooke established the collegiate Student Hour as "an hour of lecture, of lab work, or of recitation room work, for a single pupil" [3] per week (1/5 of the Carnegie Unit's 5-hour week), during a single semester (or 15 weeks, 1/2 of the Carnegie Unit's 30-week period). (The Student Hour would technically be 1/10 of the Carnegie Unit: 1/5 hour ...
Montevideo units are calculated by obtaining the peak uterine pressure amplitude and subtracting the resting tone. Then adding up those numbers generated by each contraction within a 10-minute window. For example, five contractions occurred, producing peak pressures of 55, 50, 45, 65, and 50 mm Hg, respectively.
A standard form for dates is 2021-04-10 16:31:15, which would be a mixed radix number by this definition, with the consideration that the quantities of days vary both per month, and with leap years. One proposed calendar instead uses base 13 months, quaternary weeks, and septenary days. A mixed radix numeral system is often best expressed with ...

The TU (for time unit) is a unit of time defined as 1024 μs for use in engineering. The galactic year, based on the rotation of the galaxy and usually measured in million years. [2]

The commission proposed making the standard hour the base unit of metric time, but the proposal did not gain acceptance and was eventually abandoned.

UK Credits are the same at a nominal 10 hours of learning per credit unit across CATS, the Scottish Credit and Qualifications Framework (covering higher and further education, vocational education and school qualifications in Scotland), the Credit and Qualifications Framework for Wales (ditto for Wales) and the Regulated Qualifications Framework (further education and vocational education in ...
Unlike the Egyptian system, which has units for multiples of 1, 10, 20, 40, 80, and 160 of the base unit, the Babylonian system is founded on multiples of 6 and 10, namely units of 1, 12, 24, 60, 72 (60 plus 12), 120, and 720. [1] The basic unit was the mina, which was defined as 1 sixtieth of a maris, which itself was the quantity of water ...
