The conversion of 1 volt (v) to milliamp-hours (mah) results in a value of approximately 1000 mah.
Table of Contents
This is because 1 volt applied across a 1-ohm resistor produces a current of 1,000 milliamps (or 1000 mah) flowing per hour, assuming the voltage is maintained constantly over the period. The relationship is based on the basic electrical formula where current (I) in milliamps is derived directly from voltage in volts in a simple resistive circuit.

Conversion Formula
The formula to convert volts (v) into milliamp-hours (mah) is based on Ohm’s Law and the concept of current over time. When a voltage is applied across a resistor, the current in milliamps is equal to voltage in volts multiplied by 1000 (if resistor equals 1 ohm). The calculation is:
- mah = v × 1000
This works because 1 volt across 1 ohm results in 1 amp, which equals 1000 milliamps. Over an hour, this current flows, so the total charge transferred equals current (in mah) multiplied by time in hours. For example, at 1 v across 1 ohm, the current is 1000 mah per hour.
Conversion Example
- Convert 2 volts to mah:
- Step 1: Identify the voltage, v = 2
- Step 2: Apply the formula: mah = v × 1000
- Step 3: Calculate: 2 × 1000 = 2000 mah
- Result: 2 v equals 2000 mah
- Convert 0.5 volts to mah:
- Step 1: v = 0.5
- Step 2: mah = 0.5 × 1000
- Step 3: 0.5 × 1000 = 500 mah
- Result: 0.5 v equals 500 mah
- Convert -3 volts to mah:
- Step 1: v = -3
- Step 2: mah = -3 × 1000
- Step 3: -3 × 1000 = -3000 mah
- Result: -3 v equals -3000 mah

Conversion Definitions
v
V (volt) is the SI unit of electric potential difference, measuring the energy per unit charge between two points in a circuit, indicating how much work is needed to move charge from one point to another. It is fundamental in describing electrical energy transfer.
mah
Mah (milliamp-hour) is a unit of electrical charge representing the flow of 1 milliampere of current for one hour. It is used to quantify the capacity of batteries and energy storage devices, indicating how much charge they can deliver over time.
Conversion FAQs
Can I convert voltage directly to mah without considering resistance?
No, because mah depends on the current flow over time, which is affected by resistance. To accurately convert volts to mah, you need to know the resistance of the circuit and the duration of current flow, using Ohm’s Law as a basis.
Does the conversion formula vary with different resistances?
Yes, if resistance differs, the current in milliamps changes for the same voltage. The simple formula v × 1000 applies only when resistance equals 1 ohm. For other resistances, you need to calculate current using I = V / R, then convert to mah over time.
What happens to mah calculations if voltage is negative?
Negative voltage indicates the polarity direction but does not affect the magnitude of charge in mah. The calculation considers absolute voltage values for charge transfer, so negative voltages result in negative mah, representing reverse current flow.
Is this conversion valid for AC voltage?
This conversion applies to DC voltage where current and voltage are steady. For AC, the effective or RMS voltage should be used, and calculations must consider frequency and waveform, making direct conversion more complex.
