BTU/h is often abbreviated to just BTU to represent the power of appliances. For example, an AC marked with a label of 12,000 BTU actually has a power requirement of 12,000 BTU per hour.
How do you calculate kilowatt-hour (kWh)?
1 kilowatt-hour (kWh) = 1,000 watts used for 1 hour To calculate electricity consumption: Energy (kWh) = Power (Watts) × Time (Hours) / 1000 Where: You have a 1,500-watt space heater that runs for 4 hours per day. Energy = 1500 W × 4 h / 1000 = 6 kWh per day To calculate monthly usage: 6 kWh/day × 30 days = 180 kWh per month
