Kilovolts to Millivolts formula and what each symbol means
mV = kV × 1,000,000
| Symbol | Meaning |
|---|---|
| kV | Kilovolt |
| mV | Millivolt |
Kilovolts to Millivolts examples
1 kV
1 kV × 1,000,000 = 1,000,000 mV.
10 kV
10 kV × 1,000,000 = 10,000,000 mV.
100 kV
100 kV × 1,000,000 = 100,000,000 mV.
Kilovolts compared with Millivolts
One kV is 1,000,000 times as large as one mV, so your number gets bigger when you convert kilovolts to millivolts and smaller when you convert back. If the answer is not larger than what you typed, you divided instead of multiplying.
About kilovolts and millivolts
Kilovolt (kV): Kilovolt, 1,000 V. Millivolt (mV): Millivolt, 0.001 V.
How to calculate Kilovolts to Millivolts step by step
- Enter the value in kV (the starting unit).
- Multiply by 1,000,000, because 1 kV = 1,000,000 mV.
- The product is the value in mV. To go back, divide by 1,000,000 or multiply by 0.000001.

- Dividing when you should multiply: from kV to mV multiply by 1,000,000; from mV to kV divide by 1,000,000.
Kilovolts to Millivolts FAQ
How many mV are in 1 kV?
1 kV equals 1,000,000 mV.
How many kV are in 1 mV?
1 mV equals 0.000001 kV.
Is 1 kV = 1,000,000 mV an exact conversion?
The factor is shown rounded to 7 significant figures (1,000,000). The calculator above uses more digits.
What is a millivolt (mV)?
Millivolt, 0.001 V.
How can I estimate kilovolts to millivolts in my head?
One kV is 1,000,000 times as large as one mV, so your number gets bigger when you convert kilovolts 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 250 kV in millivolts?
250 kV = 250,000,000 mV (since 250 × 1,000,000).
What is 7 kV in millivolts?
7 kV = 7,000,000 mV (since 7 × 1,000,000).
What is 40 kV in millivolts?
40 kV = 40,000,000 mV (since 40 × 1,000,000).
How many decimals should I keep when converting kV to mV?
Match the precision of your original measurement. For example, 10,000,000 mV rounds to 10,000,000 mV at 3 significant figures; keep more digits only for engineering or scientific work.
