Millivolts to Microvolts Converter

Conversion Updated 15 Jun 2026

This Millivolts to Microvolts Converter lets you convert Millivolts (mV) into Microvolts (uV) in one step. Enter a value in millivolts and you'll instantly see the equivalent in microvolts, worked out with the formula uV = mV x 1000.0000000000001. It's handy whenever you need a quick, precise millivolts-to-microvolts conversion without doing the arithmetic by hand.

  • Conversion constants are fixed and do not vary by region.

Formula

uV = mV x 1000.0000000000001
  • To convert millivolts to microvolts, multiply your value by the fixed factor 1,000 (so 1 mV = 1,000 uV).
  • The factor comes from the internationally agreed definitions of each unit, so it never changes.
  • Displayed results are rounded for readability, but the full-precision value is used in the calculation.

Example

Inputs
  • Millivolts (mV): 5000

Start with 5,000 mV. Multiply by 1,000 to get 5,000,000.000000001 uV.

Frequently asked questions

How do I convert millivolts to microvolts?
Multiply the number of millivolts by 1,000. For example, 5,000 mV equals 5,000,000.000000001 uV.
Are these conversion factors accurate?
Yes. The calculator uses internationally accepted definitions for each unit, so the conversion factor is exact.
Why can tiny differences appear after conversion?
Very small differences are only a display effect from rounding the output. The underlying calculation keeps full precision.
