How to convert volts to millivolts
A volt is a joule per coulomb. This is a unit conversion, not an AC-to-DC, peak-to-RMS, or circuit calculation. Keep the measurement reference and waveform convention consistent.
Use x for the value in V, b for the intermediate value in V, and y for the result in mV.
mV = V ÷ 0.001
Worked examples
10 V ≈ 10000 mV
Step 1: (10 × 1) ≈ 10 V.
Step 2: 10 ÷ 0.001 ≈ 10000 mV.20 V ≈ 20000 mV
Step 1: (20 × 1) ≈ 20 V.
Step 2: 20 ÷ 0.001 ≈ 20000 mV.
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
About Volts
Volts (V) measures electric potential under the conventions above. The base value in V is (x × 1), where x is the numerical value in V. Factors shown here are rounded for display; calculations use the stored factor.
About Millivolts
Millivolts (mV) measures electric potential under the conventions above. The base value in V is (x × 0.001), where x is the numerical value in mV. Factors shown here are rounded for display; calculations use the stored factor.
