Time measured = Number timer counts * Timer period

Number timer counts

Number of timer counts measured

Timer’s period in some units of (fractional) seconds

Time measured

Amount of time measured, in same units of (fractional) seconds as the Timer period

 

Time measured = Number timer counts / Timer frequency

Number timer counts

Number of timer counts measured

Timer frequency

Timer’s frequency in some units of counts per second

Time measured

Amount of time measured, in seconds
