Watts to kWh calculation

So The energy E in kilowatt-hours (kWh) is equal to the power P in watts (W), times the time period t in hours (hr) divided by 1000.

E(kWh) = P(W) × t(hr) / 1000

Example 1

What is the energy consumption in watt-hour when the power consumption is 4000 watts for time duration of 3 hours?

E = 4000W × 3h / 1000 = 12 kWh

Example 2

What is the energy consumption in watt-hour when the power consumption is 6000 watts for time duration of 3 hours?

E = 6000W × 3h / 1000 = 18 kWh

Example 3

What is the energy consumption in watt-hour when the power consumption is 7000 watts for time duration of 3 hours?

E = 7000W × 3h / 1000 = 21 kWh

Example 4

What is the energy consumption in watt-hour when the power consumption is 8000 watts for time duration of 3 hours?

E = 8000W × 3h / 1000 = 24 kWh
