Kilowatts to Kilowatt-Hours Calculator
Calculation Formula
Energy (kWh) = Power (kW) × Time (hours)
Energy Consumption
Do you know how much electricity your appliances are using? Tracking that—your air conditioner, refrigerator, washing machine, and all the rest—can save you energy and lower those electricity bills.
A kW to kWH calculator makes that process a lot simpler. If you’re paying those high electricity bills, you’re likely using more energy than you need to. By understanding how much power your appliances consume, you can optimize usage, cut costs, and improve energy efficiency.
That’s where a kW to kWH calculator comes in: it helps you monitor energy consumption for better cost management. Comparing different appliances before you buy them can also help you reduce unnecessary power usage—and save money.
Formula: How to Convert kW to kWH calculator?
The basic formula is:
Energy (kWh) = Power (kW) × Time (hours)
This formula lets you determine how much electricity an appliance consumes over a specific period.

Practical Example: Calculating Energy Usage for a Refrigerator
Let’s take a 200-watt (0.2 kW) refrigerator running for 10 hours daily.
Step-by-step calculation:
- Power Rating: 0.2 kW
- Usage Time: 10 hours
- Energy Consumption:
0.2 kW × 10 hours = 2 kWh per day
If your electricity cost is ₹8 per kWh:
🔹 Daily Cost: 2 × 8 = ₹16
🔹 Monthly Cost: ₹16 × 30 = ₹480
This calculation helps you understand and control your energy usage.
🔹 Why This Matters?
✅ Helps reduce electricity bills
✅ Aids in energy-efficient planning
✅ Prevents overloading circuits

FAQs
. 5. What is 1 kilowatt-hour kWh equal to?
How do I convert kW to kWh?
To convert kilowatts (kW) to kilowatt-hours (kWh), use this simple formula:
kWh=kW×Hours
For example, if a 2 kW heater runs for 5 hours, the energy consumed is:
2×5=10 kWh
Using a kW to kWH calculator, you can quickly estimate energy usage and electricity costs.
How many kW are in 1 kWh?
A kilowatt-hour (kWh) represents 1 kilowatt (kW) of power used for 1 hour.
1 kWh = 1 kW × 1 hour
For example, if you run a 500-watt (0.5 kW) appliance for 2 hours, it consumes:
0.5×2=1 kWh
What is 5.5 kWh equal to?
A 5.5 kWh energy usage means a device consuming 5.5 kW runs for 1 hour OR a 1 kW device runs for 5.5 hours.
Example: If an 1100-watt (1.1 kW) appliance runs for 5 hours, the total energy used is:
1.1×5=5.5 kWh
This helps calculate electricity consumption for appliances like ACs, heaters, and washing machines.
How much does 750 watts cost per hour?
The cost of running a 750-watt (0.75 kW) appliance for an hour depends on your electricity rate.
Formula:
Cost=kWh×Electricity Rate
If the rate is ₹8 per kWh, then:
0.75×8=₹6 per hour
This means a 750-watt appliance costs ₹6 per hour to run.
What is 1 kilowatt-hour kWh equal to?
A kilowatt-hour (kWh) is the energy used when a 1 kW appliance runs for 1 hour.
🔹 Examples:
✅ A 100-watt bulb running for 10 hours = 1 kWh
✅ A 500-watt TV running for 2 hours = 1 kWh
This helps in calculating electricity bills and energy savings using a kW to kWH calculator.
Conclusion: Why Use a kW to kWH calculator?
A kW to kWH calculator can make energy tracking simple and effective. By using this tool, you can cut down on electricity bills, improve energy efficiency, and make informed decisions about power usage.
