How to Calculate Running Watts for Your Refrigerator
Calculating the running watts for your refrigerator can be done using a few simple steps. Here’s how you can do it:
Step 1: Find the Rated Power Consumption
Most refrigerators will have a label that lists their rated power consumption in watts. This information is often located inside the refrigerator or on the back. If the label displays amperes instead of watts, you can convert it using the formula:
Watts = Amps x Volts
Here’s a quick breakdown:
- A typical household in North America operates on a voltage of about 120 volts.
- So if your refrigerator uses 10 amps, the calculation would look like this:
Watts = 10 Amps x 120 Volts = 1200 Watts
Step 2: Account for the Duty Cycle
Refrigerators do not run continuously; they cycle on and off to maintain a consistent temperature. This is known as the duty cycle. To estimate your refrigerator’s operating cost, you can gauge the average running time over a 24-hour period.
For example, if your refrigerator operates for about 8 hours per day:
Daily Running Watts = (Running Watts x Hours Used Per Day)
Using the previous example of 1200 watts:
Daily Running Watts = 1200 Watts x 8 Hours = 9600 Watt-hours per day
Step 3: Convert to Kilowatt-Hours
Electricity usage is usually measured in kilowatt-hours (kWh). To convert watt-hours to kilowatt-hours, divide by 1000:
Kilowatt-Hours = Watt-Hours / 1000
So in our example:
Kilowatt-Hours = 9600 Wh / 1000 = 9.6 kWh
