Calculating daily usage cost: multiply wattage by hours of usage, then divide by 1000
Electric blankets are a great way to keep warm, especially during the cold winter months. They are generally energy-efficient, consuming relatively low amounts of power, typically between 15 to 200 watts of power per hour, with an average usage of around 100 to 150 watts.
To calculate the daily usage cost of your electric blanket, you can use the following formula:
Wattage x Hours Used/1000 x Cost per kWh = Daily Cost
Let's break this down:
Firstly, you need to know the wattage of your electric blanket. This can vary depending on the settings, size, and temperature conditions, so it's important to check the manufacturer's specifications. Most electric blankets range from 15 to 200 watts, with an average of 100 to 150 watts.
Next, determine the number of hours you use the blanket each day. This will be an important factor in calculating your daily energy consumption.
Now, you can multiply the wattage by the hours of usage. For example, if you have a 150-watt electric blanket and use it for 6 hours a day:
150 watts x 6 hours = 900 watt-hours
To convert watt-hours to kilowatt-hours (kWh), divide the result by 1000:
900 watt-hours / 1000 = 0.9 kWh
Finally, to get the daily cost, multiply the result by the cost of electricity in your region, which is usually measured in cents or pence per kWh. For example, if electricity costs 15 cents per kWh:
9 kWh x 15 cents = $0.135
So, the daily cost of using a 150-watt electric blanket for 6 hours a day, with electricity costing 15 cents per kWh, would be approximately $0.135.
You can also calculate the monthly and yearly costs by multiplying the daily cost by the number of days of usage per month and then by 12 for the yearly cost.
It's important to note that actual costs may vary, and you can use programmable timers or lower temperature settings to help save on energy costs.
