megahertz to nanohertz
Convert megahertz (MHz) to nanohertz (nHz). Use an editable frequency converter, conversion formula, and reference table.
1 MHz = 1e+15 nHz
Conversion formula
One megahertz equals 1e+15 nanohertz. Multiply your value in megahertz by this factor to get nanohertz. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 megahertz:5 × 1e+15 = 5e+15 nHz

About these measurements
Frequency measures cycles per second.
The base reference used here is the hertz. One megahertz is 1,000,000 base units; one nanohertz is 1e-9 base units.
Important distinctions
Frequency is the reciprocal of period, not angular velocity.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
How do I convert MHz to nHz?
Multiply the quantity in MHz by 1e+15. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the nanohertz to megahertz converter.
