HztoMHz

Convert hertz (Hz) to megahertz (MHz).

Factor1 Hz = 1e-6 MHz

Converter

Hz

Accepts numbers or expressions, e.g. 150 + 14.7

Result
1MHz

Rendered to 6 significant figures.

Formula

Formula
MHz = Hz × 1e-6

Multiply any value in hertz by 1e-6 to obtain the value in megahertz.

Worked example

Convert 1.00000e+6 Hz to MHz.

  1. 01Start with 1.00000e+6 Hz.
  2. 02Multiply by the conversion factor: 1.00000e+6 × 1e-6 = 1 MHz.
Result1.00000e+6 Hz = 1 MHz

FAQ

What is the conversion factor from Hz to MHz?
1 Hz equals 1e-6 MHz. To convert, multiply the value in hertz by 1e-6.
How do I convert 1 Hz to MHz?
1 Hz = 1e-6 MHz. For any value, multiply by 1e-6.
How do I convert MHz back to Hz?
Divide by the same factor — or equivalently, multiply by 1000000. So 1 MHz = 1.00000e+6 Hz.
When would I need to convert hertz to megahertz?
Frequency conversions between Hz and MHz are needed in signal and RF engineering, motor and turbomachinery rotational-speed work, vibration and pulse-rate analysis, and control-loop sample-rate specification. Hz dominates electronics and instrumentation; kHz, MHz and GHz cover audio through microwave; rpm and rps dominate mechanical rotational equipment; cycles per minute, second and hour cover slow industrial cyclic processes. Angular frequency (rad/s) and time-period (Hz ↔ seconds) conversions are NOT included — they require either a 2π factor or a reciprocal relationship.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
