Millisecond

A unit of 10 milliseconds may be called a centisecond, and one of 100 milliseconds a decisecond, but these names are rarely used.^[3] To help compare

Horizontal logarithmic scale marked with units of time

Examples

The Apollo Guidance Computer used metric units internally, with centiseconds used for time calculation and measurement.^[4]
