900 mAh equals approximately 0.0037 volts. This conversion is based on the assumption of a typical battery voltage and capacity.
To convert milliamp-hours (mAh) to volts, you need to understand the relationship between charge capacity and voltage. Since mAh measures how much charge a battery holds, and volts measure the electrical potential difference, the conversion requires knowing the battery’s voltage. Without voltage info, you can’t directly convert mAh to volts; however, if you assume a standard voltage, such as 3.7V for a lithium-ion cell, you can estimate the voltage equivalent based on the capacity. In this case, 900 mAh at 3.7V corresponds to a certain energy content, but strictly speaking, mAh alone doesn’t convert directly to volts without voltage context.

Conversion Formula
The conversion from mah to volts relies on the formula: Voltage = (Capacity in mAh * Nominal Voltage) / 1000. This formula works because mAh measures the stored charge, and multiplying by the nominal voltage gives the energy in milli-watt-hours, which can be related to volts when dividing by capacity. For example, if a battery has 900 mAh and 3.7V:
- Multiply 900 mAh by 3.7V: 900 * 3.7 = 3330 mWh
- Divide 3330 mWh by 1000 to get 3.33 Wh
- To find volts, divide watt-hours by capacity in Ah (which is mAh divided by 1000): 3.33 Wh / 0.9 Ah = 3.7V
This shows how capacity and voltage relate through energy content, but be aware that actual voltage varies during discharge, so this is a simplified model.
Conversion Example
- Example 1: 1500 mAh at 3.7V:
- Multiply 1500 by 3.7: 1500 * 3.7 = 5550 mWh
- Divide 5550 by 1000: 5.55 Wh
- Convert capacity: 1500 mAh = 1.5 Ah
- Voltage remains 3.7V as this is a standard assumption
- Example 2: 500 mAh at 3.7V:
- Multiply 500 by 3.7: 1850 mWh
- Divide 1850 by 1000: 1.85 Wh
- Example 3: 1000 mAh at 3.7V:
- Multiply 1000 by 3.7: 3700 mWh
- Divide 3700 by 1000: 3.7 Wh

Conversion Definitions
mAh: Milliamp-hours measure the electric charge a battery can deliver over time. It indicates capacity, showing how much current a battery supplies multiplied by the duration until depletion, crucial for comparing battery life in portable devices.
Volts: Volts measure electrical potential difference between two points, representing the energy per unit charge. In batteries, volts determine the voltage level, influencing device compatibility and performance.
Conversion FAQs
Can I convert 900 mAh directly to volts?
No, because mAh measures capacity, and volts measures potential difference. To relate them, you need the battery’s voltage rating. Without voltage info, only capacity can be known, not the voltage.
Why is the voltage assumption of 3.7V used in these conversions?
The 3.7V value is a common nominal voltage for lithium-ion batteries, which are widely used in portable electronics. Using this simplifies calculations, but actual voltage may vary during discharge, so the estimate is approximate.
How accurate is the conversion from mAh to volts shown here?
The conversion provides an estimate based on a standard voltage, but real-world voltage varies during discharge, and different battery chemistries have different nominal voltages. Thus, it should be considered an approximation.
Can I use this method for other battery types?
Yes, but only if you know the nominal voltage for that battery type. For example, alkaline batteries have different voltages, so the conversion must be adjusted accordingly.
Is there a way to convert mAh to volts without knowing the battery voltage?
Not directly, because mAh alone does not indicate voltage. You need the voltage rating as part of the battery’s specifications to convert capacity to energy or voltage estimates.
