Amp-Hours to Kilowatt-Hours Calculator
Convert Amp-Hours (Ah) to Kilowatt-Hours (kWh) with this easy-to-use calculator.
To choose a battery for your RV or figure out how much power your solar panels can store, you need to know how many Amp-Hours (Ah) and kilowatt-hours (kWh)
Amp-hours (Ah) tell you how long a battery can power something. Kilowatt-hours (kWh) measure the total amount of energy used or stored.
It is important to know how to convert Ah to kWh when comparing different energy options..
Our simple Ah to kWh calculator makes this conversion quick and easy. Use it to switch between these units and understand your energy needs easily.
What are Amp-Hours (Ah) and Kilowatt-Hours (kWh)?
Amp-Hours (Ah) is a way to measure the capacity of a battery. It tells you how much electric charge a battery can store or deliver.
Think of it as the size of a fuel tank in your car—bigger tanks let you travel farther, and higher Ah batteries can power devices for longer.
- Batteries: Commonly found on car batteries, power banks, and solar systems.
- Electronics: Helps determine how long a device can run on a full charge.
Imagine a 10 Ah battery. Connecting a device with 1 amp of current will run for 10 hours before the battery is empty. If your device uses two amps, the same battery will last only 5 hours.
Kilowatt-hours (kWh) measure energy usage. It tells you how much electricity is consumed or stored over time. This is the unit you often see on your electricity bill.
- kWh calculates the total power consumption of appliances, devices, or households.
- It combines the amount of power (watts) and the time it’s used.
If you use a 100-watt light bulb for 10 hours, it will consume 1 kWh of energy. Similarly, a 1,000-watt (1 kilowatt) appliance running for 1 hour also uses 1 kWh.
How to Convert Microohms to Ohms
👋 Curious about how microohms relate to ohms? Let’s break it down! 🚀
Microohms to Ohms Formula ✨
Quick Trick: To convert microohms to ohms, multiply by 10-6!
Understanding the Conversion
The formula to convert microohms to ohms is:
Ω = µΩ × 10-6
Where:
- Ω is the resistance in ohms
- µΩ is the resistance in microohms
To convert microohms to ohms, simply multiply the value in microohms by 10-6.

Kiloohms (kΩ) and Ohms (Ω) are units of electrical resistance. The prefix ‘kilo’ means 1000, so:
This relationship is similar to other metric prefixes like kilometers to meters.
Amp-hours (Ah) and milliamp-hours (mAh) both measure electric charge, but they use different scales. One amp-hour (1 Ah) is equal to 1000 milliamp-hours (1000 mAh). So, a 10 Ah battery has the same capacity as a 10,000 mAh battery. mAh is often used for smaller batteries, like those in cell phones and laptops, while Ah is used for larger batteries, like car batteries or deep-cycle batteries.
Not exactly. A higher Ah rating means the battery can deliver a certain amount of current for a longer period. It indicates the battery’s capacity, not its power output. Power (measured in watts or kilowatts) is related to both current (amps) and voltage. A battery with a higher Ah rating at the same voltage will generally provide power for longer than a battery with a lower Ah rating.
The voltage is usually printed directly on the battery label. Look for a number followed by “V” (e.g., 12V, 6V, 3.7V). If it’s not readily visible, consult the battery’s documentation or the device it powers.
No. You can’t directly convert Ah to watts (W) or kilowatts (kW). Ah measures charge, while watts and kilowatts measure power. To convert Ah to power (and subsequently to kWh), you need to know the voltage (V) of the battery. The formula for power is: Power (W) = Voltage (V) * Current (A).
Voltage is crucial because it represents the “push” of the electrical current. A higher voltage means more energy is transferred per unit of charge. Therefore, the same Ah rating at a higher voltage will result in a higher kWh value (more total energy).
First, you need the battery’s voltage. Then, calculate the current (Amps) the device draws using the formula: Current (A) = Power (W) / Voltage (V). Once you have the current, you can estimate the runtime by dividing the battery’s Ah rating by the device’s current draw: Runtime (hours) = Battery Ah / Device Current (A). This is an estimate as real-world conditions can affect battery performance.
Think of it this way: You’re converting “amp-hours” to “kilo-watt-hours.” You need to introduce voltage (V) to get to watts (V * A = W). Then, since you want kilo-watt-hours, you divide by 1000: kWh = (Ah * V) / 1000.
