What is kWh (kWh)?
The kilowatt-hour (kWh) is 1,000 watt-hours (3.6 MJ) and the unit on your electricity bill. A typical home uses several kWh per day.

The British thermal unit (BTU) is roughly the energy to heat one pound of water by 1 °F, about 1,055 joules. It rates heating, boilers and air conditioners, especially in the US.
Why convert kWh to BTU?
Energy units come from different fields: joules and kilojoules in physics, kilocalories on food labels, kilowatt-hours on electricity bills, BTU in heating and air-conditioning. Converting between them is common for nutrition, utility bills and HVAC.
One kilocalorie (the food Calorie) equals exactly 4.184 kJ — which is why nutrition labels show both. One kilowatt-hour is 3.6 MJ, equal to about 3,412 BTU or 860 kcal (BIPM/ISO).
