How to use this calculator
- Enter frequency in Hz.
- Select Calculate and keep the output unit with the answer.
Before you use the answer
Check the component connections and unit prefixes before copying a result into a circuit notebook. These tools describe ideal, introductory circuits. They do not replace datasheets, thermal checks, isolation requirements or qualified design work, and they are not intended for mains installation decisions.
The output is milliseconds rather than seconds.

Why might a result be approximate?
Measurement uncertainty, ideal-model assumptions and floating-point rounding can all matter. Displaying more digits does not improve the original measurement.
