Core equations used by this converter.

V → mVmV = V × 1000
Exact factor1 V = 1000 mV
mV → VV = mV ÷ 1000
iLinear conversion using factor 1000. Prefer the exact factor over rounded multipliers when precision matters.

How to use

1

Choose V → mV or mV → V

Use the tabs to switch direction. Forward mode needs volts; reverse uses the opposite unit.

2

Enter the value

Type a non-negative value in the active unit field.

3

Convert and read the result

Use Convert or let the result update automatically.
