How many volts are in one millivolt?

There are 0.001 volts in 1 millivolt.

How do you convert volts to millivolts?

Multiply the number of volts by 1,000 — or use the formula mV = V × 1,000.

What is 6 volts in millivolts?

6 volts is 6,000 millivolts. 6 × 1,000 = 6,000 millivolts.

Is the volts to millivolts conversion exact?

Yes. The relationship is fixed by definition, so 1,000 is an exact conversion factor — only the displayed result is rounded.

1 volt = 1,000 millivolts

Volts to Millivolts formula

mV = V × 1,000

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

Worked examples

2 volts = 2,000 millivolts — 2 × 1,000 = 2,000 millivolts
6 volts = 6,000 millivolts — 6 × 1,000 = 6,000 millivolts
10 volts = 10,000 millivolts — 10 × 1,000 = 10,000 millivolts

When you need to convert volts to millivolts

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 volt = 1,000 millivolts, the answer should be larger 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

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.
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.
