## User Guide

This tool will convert the period to the equivalent frequency value, by calculating the number of cycles or revolutions per unit period of time from the time it takes to complete one full cycle or revolution.

For each new period entered an updated conversion scale will display with a range of period to frequency conversion values centered around the converted frequency.

### Formula

The formula used to calculate the frequency is:

#### Wave or Rotational Frequency

f = 1 / T

#### Angular Frequency

ω = 2 · π / T (radians)

ω = 360 / T (degrees)

#### Symbols

- f = Frequency
- ω = Angular frequency
- T = Period
- π = Pi (constant)

### Period Measured

Enter the amount of time it takes to complete one full cycle or revolution.

### Frequency Calculation

This is the number of cycles or revolutions per unit period of time, which corresponds to the entered time period.

## Help

### 1-10 ms to Hz

*What are the Hz values for a period varying from 1-10 ms?*

This conversion scale shows the equivalent frequency values for a period range from 1 to 10 milliseconds:
