Watt-hour (Wh) Calculator
👋 Welcome to the Watt-hour (Wh) Calculator! This tool helps you calculate watt-hours based on amp-hours or time. 🚀
Calculate Watt-hours from Amp-hours
To calculate watt-hours from amp-hours, you can use the following formula:
Wh = Ah × VWhere:
- Wh = Watt-hours
- Ah = Ampere-hours
- V = Voltage (in volts)
For example, if you have a battery rated at 10 Ah and operates at 12V, the calculation would be:
Wh = 10 Ah × 12 = 120 WhCalculate Watt-hours from Time
To calculate watt-hours based on power consumption over time, use the following formula:
Wh = W × hWhere:
- Wh = Watt-hours
- W = Power in watts
- h = Time in hours
For example, if you run a 100-watt appliance for 3 hours, the calculation would be:
Wh = 100 W × 3 h = 300 WhUnderstanding Watt-hours (Wh)
What is a Watt-hour (Wh)?
A watt-hour (Wh) is a unit of energy that measures the amount of work done or energy consumed over time. It represents the energy used when one watt of power is consumed for one hour. For example, a 60-watt light bulb running for one hour uses 60 Wh of energy.
Why Calculate Watt-hours?
Calculating watt-hours is essential for understanding energy consumption and efficiency. It helps you determine how much energy your devices use, allowing for better energy management and cost savings.
Practical Applications
Knowing how to calculate watt-hours can help you in various scenarios, such as sizing batteries for solar systems, estimating energy costs, and optimizing the use of electrical appliances.
