180 mah is approximately 0.00054 volts when converted.
This conversion assumes a typical voltage for a lithium-ion battery cell, which is about 3.0 volts per 1000 mah. To find volts from mah, we divide the capacity in mah by 1000 and multiply by the cell voltage. So, 180 mah equals (180/1000) * 3.0 ≈ 0.54 volts.
Introduction to Mah to Volts Conversion
The process of converting milliamp-hours to volts involves understanding the relationship between battery capacity and voltage. Since mah measures how much charge a battery can hold, and volts indicate the electrical potential, converting requires knowing the voltage per unit capacity. In most cases, for lithium-ion cells, 3.0 volts per 1000 mah is used as standard.

Conversion Formula
To convert mah to volts, you divide the milliamp-hours by 1000 to get amp-hours, then multiply by the voltage of the battery cell. The formula is: volts = (mah / 1000) * cell voltage. For example, for 180 mah, volts = (180 / 1000) * 3.0 = 0.54 volts. This works because capacity in mah measures charge, and multiplying by voltage gives energy potential.
Conversion Example
- Convert 200 mah to volts:
- Divide 200 by 1000: 0.2 amp-hours.
- Multiply by 3.0 volts: 0.2 * 3.0 = 0.6 volts.
- Convert 150 mah to volts:
- 150 / 1000 = 0.15 amp-hours.
- 0.15 * 3.0 = 0.45 volts.
- Convert 250 mah to volts:
- 250 / 1000 = 0.25 amp-hours.
- 0.25 * 3.0 = 0.75 volts.
- Convert 100 mah to volts:
- 100 / 1000 = 0.1 amp-hours.
- 0.1 * 3.0 = 0.3 volts.
- Convert 300 mah to volts:
- 300 / 1000 = 0.3 amp-hours.
- 0.3 * 3.0 = 0.9 volts.

Conversion Definitions
mah
Mah, or milliamp-hours, measures the total charge a battery can deliver over time. It indicates how long a device can run before needing recharge, by representing the capacity in thousandths of an amp-hour. Higher mah generally means longer battery life in devices.
volts
Volts measure the electrical potential difference between two points, reflecting the energy per unit charge in a circuit. It determines how much force pushes electrons through a conductor, influencing the power output and compatibility of batteries with devices.
Conversion FAQs
How accurate is the mah to volts conversion?
The conversion provides an approximation based on typical battery voltages, such as 3.0 volts per 1000 mah for lithium-ion cells. Actual voltage may vary depending on battery chemistry, age, and load conditions, so for precise applications, measure with a multimeter.
Can I convert mah to volts for all types of batteries?
No, this conversion is most accurate for lithium-ion batteries with a standard voltage around 3.0 volts per 1000 mah. Other batteries like nickel-metal hydride or lead-acid have different voltages, requiring different conversion factors.
Why does the voltage stay constant during discharge?
Many batteries, especially lithium-ion ones, maintain a relatively stable voltage until nearly depleted. This is because the electrochemical reactions sustain a steady potential until the battery approaches exhaustion, after which voltage drops sharply.
Is mah a measure of energy or power?
Mah measures capacity or stored charge, indicating how much current a battery can supply over time. Power, measured in watts, combines voltage and current, representing the rate of energy transfer. Both are related but distinct concepts.
