multiply by 1,000
50 mHz = 50,000 µHz
millihertz to microhertz formula
Milli is 10^-3 and micro is 10^-6. They are three powers of ten apart, so every mHz to µHz conversion uses the exact factor 1,000.
µHz = mHz × 1,000
50 mHz × 1,000 = 50,000 µHzmHz to µHz table

Understanding millihertz and microhertz
A millihertz (mHz) is 10⁻³ of the base unit (hertz) and a microhertz (µHz) is 10⁻⁶. They sit three powers of ten apart, so going from mHz to µHz means multiplying by exactly 1,000 — move the decimal point three places to the right.
Millihertz describe slow cyclic phenomena: ocean swell around 100 mHz, heart-rate variability bands, building sway, and long-period seismic energy. A 1 mHz signal has a period of about 17 minutes, so measuring one means committing to a long record.
This calculator shifts the decimal exponent rather than multiplying in binary floating point, so 50 mHz returns exactly 50,000 µHz — not a value with a trailing rounding error.
Common mHz to µHz mistake
Frequency resolution is bounded by observation time: resolving 1 µHz requires at least about 11.6 days of continuous data. Converting into µHz does not create resolution the record never contained.
When to use mHz vs µHz
millihertz and microhertz are used in seismology, ocean wave analysis, astrophysics, ultra-low frequency sensors, and cardiac rhythm monitoring. Use the larger milli unit when the number becomes easier to scan, and the smaller micro unit when you need finer detail.
