# Volts to dBµV online calculator & Python code

Use this online calculator to convert a voltage in Volts to a voltage in dBµV.

TechOverflow calculators:
You can enter values with SI suffixes like 12.2m (equivalent to 0.012) or 14k (14000) or 32u (0.000032).
The results are calculated while you type and shown directly below the calculator, so there is no need to press return or click on a Calculate button. Just make sure that all inputs are green by entering valid values.

V

#### Formula:

$$U_{\text{dBµV}} = \frac{20\cdot\log(1\,000\,000 \cdot U_V)}{ \log(2) + \log(5)}$$

#### Python code:

import math
def volts_to_dbuv(v):
"""Convert a voltage in volts to a voltage in dBµV"""
return (20*math.log(1e6 * v))/(math.log(2) + math.log(5))
