How many millivolts are in one volt?

There are 1,000 millivolts in 1 volt.

How do you convert millivolts to volts?

Multiply the number of millivolts by 0.001 — or use the formula V = mV ÷ 1,000.

What is 6 millivolts in volts?

6 millivolts is 0.006 volts. 6 ÷ 1,000 = 0.006 volts.

Is the millivolts to volts conversion exact?

Yes. The relationship is fixed by definition, so 0.001 is an exact conversion factor — only the displayed result is rounded.

1 millivolt = 0.001 volts

Millivolts to Volts formula

V = mV ÷ 1,000

The millivolts to volts conversion factor is 0.001, which is exact by definition. 1 millivolt = 0.001 volts, and 1 volt = 1,000 millivolts.

Worked examples

2 millivolts = 0.002 volts — 2 ÷ 1,000 = 0.002 volts
6 millivolts = 0.006 volts — 6 ÷ 1,000 = 0.006 volts
10 millivolts = 0.01 volts — 10 ÷ 1,000 = 0.01 volts

When you need to convert millivolts to volts

Comparing specifications written for a different market.
Checking a figure quoted in an unfamiliar unit before acting on it.
Converting values consistently across a spreadsheet, report or shopping list.

Common mistakes to avoid

Dividing when you should multiply. Because 1 millivolt = 0.001 volts, the answer should be smaller than the number you started with.
Rounding too early. Convert first at full precision, then round the final answer to the precision the task actually needs.

How precise does the answer need to be?

Round only at the end, and only to the precision your task actually needs. The converter above keeps full double precision internally and rounds for display.

How these units are defined

Millivolt (mV): One thousandth of a volt. This unit's relationship to the SI base unit is exact by definition, so no rounding enters the conversion factor.
Volt (V): The SI unit of electric potential. This unit's relationship to the SI base unit is exact by definition, so no rounding enters the conversion factor.
