Centi-(symbol c) is a unit prefix in the metric system denoting a factor of one hundredth. Proposed in 1793, [ 1 ] and adopted in 1795, the prefix comes from the Latin centum , meaning "hundred" ( cf. century, cent, percent, centennial).
A metric prefix is a unit prefix that precedes a basic unit of measure to indicate a multiple or submultiple of the unit. All metric prefixes used today are decadic.Each prefix has a unique symbol that is prepended to any unit symbol.
For example, a hundredth of 675 is 6.75. In this manner it is used with the prefix "centi-" such as in centimeter. A hundredth is also one percent. A hundredth is the reciprocal of 100. A hundredth is written as a decimal fraction as 0.01, and as a vulgar fraction as 1/100. [2]
The poise is often used with the metric prefix centi-because the viscosity of water at 20 °C (standard conditions for temperature and pressure) is almost exactly 1 centipoise. [3] A centipoise is one hundredth of a poise, or one millipascal-second (mPa⋅s) in SI units (1 cP = 10 −3 Pa⋅s = 1 mPa⋅s). [4] The CGS symbol for the centipoise ...
A binary prefix indicates multiplication by a power of two. The tenth power of 2 (2 10 ) has the value 1024 , which is close to 1000 . This has prompted the use of the metric prefixes kilo , mega , and giga to also denote the powers of 1024 which is common in information technology with the unit of digital information, the byte .
Numerical prefixes occur in 19th-, 20th-, and 21st-century coinages, mainly the terms that are used in relation to or that are the names of technological innovations, such as hexadecimal and bicycle. Also used in medals that commemorate an anniversary , such as sesquicentennial (150 years), centennial (100 years), or bicentennial (200 years).
Now, it’s time to put it all together. Here are three sample check amounts, with examples of how to write them out correctly: $1,750: One thousand, seven hundred fifty and 00/100
The exact modern SI definition is "[The second] is defined by taking the fixed numerical value of the cesium frequency, Δν Cs, the unperturbed ground-state hyperfine transition frequency of the cesium 133 atom, to be 9 192 631 770 when expressed in the unit Hz, which is equal to s −1." [1]
