The conversion of 180 mah to volts results in approximately 0.0005 volts, based on typical assumptions about battery voltage. This small voltage indicates the limited energy output of a 180 milliamp-hour battery when measured in volts.
Table of Contents
To convert mah (milliamp-hours) to volts, you need to know the battery’s capacity (mah) and its voltage rating. Since mah measures capacity and volts measure potential difference, the conversion usually involves the battery’s voltage. For example, if a battery has 180 mah and a voltage of 3.7V, then its energy in volts can be estimated by this simple multiplication: volts = capacity (mah) * voltage / 1000. This reflects how much energy is stored in the battery in terms of voltage and capacity.

Conversion Formula
The formula to convert mah to volts relies on knowing the battery’s voltage rating, which is usually fixed for a given cell type. The basic calculation multiplies the capacity (mah) by the voltage (V), then divides by 1000 to convert milliamp-hours into amp-hours, resulting in the energy in volt-ampere-hours, or volts. For example, a 180 mah battery with 3.7V is calculated as 180 * 3.7 / 1000 = 0.666 volts. This formula works because it relates the capacity in milliamp-hours, which measures stored charge, with the voltage, indicating electrical potential.
Conversion Example
- Suppose you have a 200 mah battery with a voltage of 3.7V.
- Step 1: Multiply 200 mah by 3.7V: 200 * 3.7 = 740.
- Step 2: Divide by 1000 to convert mah to amp-hours: 740 / 1000 = 0.74.
- Result: The energy equals approximately 0.74 volts.
- If a battery has 150 mah capacity and 3.7V voltage:
- Step 1: 150 * 3.7 = 555.
- Step 2: 555 / 1000 = 0.555.
- Result: The energy amount is 0.555 volts.
- For a 300 mah battery at 3.7V:
- Step 1: 300 * 3.7 = 1110.
- Step 2: 1110 / 1000 = 1.11.
- Result: Energy equals 1.11 volts.

Conversion Definitions
mah
Mah (milliamp-hours) is a measure of a battery’s capacity, indicating how much charge it can store and deliver over time. It describes the total amount of current a battery can supply multiplied by the duration in hours, reflecting its energy storage potential.
volts
Volts (V) is a unit of electric potential difference between two points. It measures the force that drives electric current through a circuit. In batteries, volts indicate the electrical pressure available to power devices.
Conversion FAQs
How do I convert mah to volts if I know the battery’s voltage?
To convert mah to volts, multiply the capacity in mah by the battery’s voltage and divide by 1000. For example, with a 180 mah capacity and 3.7V, the calculation is 180 * 3.7 / 1000 = 0.666 volts. This gives an estimate of the energy in volts for that capacity.
Can I convert mah directly to volts without knowing the voltage rating?
No, because mah measures capacity, while volts measures potential difference. Without knowing the voltage of the battery, you cannot accurately convert mah to volts. The conversion requires that voltage value for meaningful results.
Why is the voltage value important in these conversions?
Voltage determines the electrical potential difference that a battery can provide. It directly influences how much energy a battery can supply. Without voltage, mah alone cannot describe the battery’s energy output in volts.
