Microvolts to Millivolts formula and what each symbol means
mV = µV × 0.001
| Symbol | Meaning |
|---|---|
| µV | Microvolt |
| mV | Millivolt |
Microvolts to Millivolts examples
1 µV
1 µV × 0.001 = 0.001 mV.
10 µV
10 µV × 0.001 = 0.01 mV.
100 µV
100 µV × 0.001 = 0.1 mV.
Microvolts compared with Millivolts
One mV is 1,000 times as large as one µV, so your number gets smaller when you convert microvolts to millivolts and bigger when you convert back. If the answer is not smaller than what you typed, you multiplied instead of dividing.
About microvolts and millivolts
Microvolt (µV): Microvolt, 1×10⁻⁶ V. Millivolt (mV): Millivolt, 0.001 V.
How to calculate Microvolts to Millivolts step by step
- Enter the value in µV (the starting unit).
- Multiply by 0.001, because 1 µV = 0.001 mV.
- The product is the value in mV. To go back, divide by 0.001 or multiply by 1,000.

- Dividing when you should multiply: from µV to mV multiply by 0.001; from mV to µV divide by 0.001.
Microvolts to Millivolts FAQ
How many mV are in 1 µV?
1 µV equals 0.001 mV.
How many µV are in 1 mV?
1 mV equals 1,000 µV.
Is 1 µV = 0.001 mV an exact conversion?
The factor is shown rounded to 7 significant figures (0.001). The calculator above uses more digits.
What is a millivolt (mV)?
Millivolt, 0.001 V.
How can I estimate microvolts to millivolts in my head?
One mV is 1,000 times as large as one µV, so your number gets smaller when you convert microvolts to millivolts and bigger when you convert back. If the answer is not smaller than what you typed, you multiplied instead of dividing.
What is 40 µV in millivolts?
40 µV = 0.04 mV (since 40 × 0.001).
What is 200 µV in millivolts?
200 µV = 0.2 mV (since 200 × 0.001).
What is 3 µV in millivolts?
3 µV = 0.003 mV (since 3 × 0.001).
How many decimals should I keep when converting µV to mV?
Match the precision of your original measurement. For example, 0.01 mV rounds to 0.01 mV at 3 significant figures; keep more digits only for engineering or scientific work.
