mV → VV = mV ÷ 1000

Exact factor1 V = 1000 mV

V → mVmV = V × 1000

iLinear conversion using factor 1/1000. Prefer the exact factor over rounded multipliers when precision matters.

How to use

1

Choose mV → V or V → mV

Use the tabs to switch direction. Forward mode needs millivolts; 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.

1000 mV to volts

1000 mV to volts

1000 ÷ 1000 = 1 V

1 V

ϟ

500 mV to volts

500 mV to volts

500 ÷ 1000 = 0.5 V

0.5 V

ϟ

3.3 mV to volts

3.3 mV to volts

3.3 ÷ 1000 = 0.0033 V

0.0033 V
