MHz to ns Conversion Calculator

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

Enter the frequency in MHz.

๐Ÿ” ns to MHz


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)


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 (ยตs), or nanoseconds (ns).
