# Mah to Watt Hour Converter

An ampere-hour is a unit of electric charge. Milliampere is one-thousandth of an ampere-hour (3.6 coulombs). It is denoted as mAh. It is used in measurements of electrochemical systems such as electroplating. Use this online Mah Battery Life Calculator to convert milliampere hours to watt hours.Watt-hours is milliamp-hours times volts divided by 1000 (Wh = mAh × V / 1000). Hence mAh = Wh / (V x 1000). Mah to Watt hour converter is useful in determining the battery life.

Mah to Watt hour converter is useful in determining the battery life.

#### Formula:

Watt Hour = ( Milli Amp Hours × Volts ) / 1000

### Example:

Calculate the Watts Hours of a battery having 50Mah and 5V?

#### Solution:

Watt Hour = ( 50 × 5 ) / 1000
= 0.25Wh
