This tool calculates** nanosecond** (ns) from the frequency in **Megahertz** (MHz).

Enter the frequency in MHz.

## Formula

The period T is the inverse of frequency f

**T (seconds) = 1/f (Hz)**

**T (seconds) = [1/f]*10 ^{-9} (GHz)**

**T (nanoseconds) = 1/f (GHz)**

Since

**1 GHz = 1000 MHz**

**T (nanoseconds) = 1000/f (MHz)**

**Example Calculations**

- A frequency value of 50 MHz is equivalent to 20 ns
- A frequency of 100 MHz is equivalent to 10 ns

**Understanding Frequency and Period**

**Frequency** is the number of occurrences of a repeating event per unit of time. It is commonly measured in hertz (Hz), with one hertz equal to one cycle per second. Higher frequencies are often measured in kilohertz (kHz), megahertz (MHz), or gigahertz (GHz).

**1 MHz**equals**1,000,000**cycles per second.

**Period** is the duration of one complete cycle of a repeating event, and it is the reciprocal of the frequency. It is measured in units of time such as seconds, milliseconds (ms), microseconds (µs), or nanoseconds (ns).
