ok so how to calculate the RC time?It all depends upon the type of monostable circuit. For the common 555 timer the output pulse duration, when triggered, is approximately equal to the RC time-constant of the timing components.

ok, so how to calculate the RC time?
well explain cowboybob , actually i am calculating 1 uF as 1. but now i know that 1 uF is equal to 0.000001. thanx all.1.1 times R times C yields time constant (TC) in seconds. R is in ohms and C is in uF.
E.G., 1Mohm resister and a 1uF cap: 1,000,000 X 0.000001 X 1.1 = 1.1 second TC.
Given that there is always some slop in the stated values of most R and C components, your actual TC will vary slightly.
