Volts to Millivolts formula and what each symbol means
mV = V × 1,000
| Symbol | Meaning |
|---|---|
| V | Volt |
| mV | Millivolt |
Volts to Millivolts examples
1 V
1 V × 1,000 = 1,000 mV.
10 V
10 V × 1,000 = 10,000 mV.
100 V
100 V × 1,000 = 100,000 mV.
Volts compared with Millivolts
One V is 1,000 times as large as one mV, so your number gets bigger when you convert volts to millivolts and smaller when you convert back. If the answer is not larger than what you typed, you divided instead of multiplying.
About volts and millivolts
Volt (V): The volt, the SI unit of electric potential. Millivolt (mV): Millivolt, 0.001 V.
How to calculate Volts to Millivolts step by step
- Enter the value in V (the starting unit).
- Multiply by 1,000, because 1 V = 1,000 mV.
- The product is the value in mV. To go back, divide by 1,000 or multiply by 0.001.

Volts to Millivolts FAQ
How many mV are in 1 V?
1 V equals 1,000 mV.
How many V are in 1 mV?
1 mV equals 0.001 V.
Is 1 V = 1,000 mV an exact conversion?
The factor is shown rounded to 7 significant figures (1,000). The calculator above uses more digits.
What is a volt (V)?
The volt, the SI unit of electric potential.
How can I estimate volts to millivolts in my head?
One V is 1,000 times as large as one mV, so your number gets bigger when you convert volts to millivolts and smaller when you convert back. If the answer is not larger than what you typed, you divided instead of multiplying.
What is 60 V in millivolts?
60 V = 60,000 mV (since 60 × 1,000).
What is 250 V in millivolts?
250 V = 250,000 mV (since 250 × 1,000).
What is 7 V in millivolts?
7 V = 7,000 mV (since 7 × 1,000).
How many decimals should I keep when converting V to mV?
Match the precision of your original measurement. For example, 10,000 mV rounds to 10,000 mV at 3 significant figures; keep more digits only for engineering or scientific work.
