How many watts are equal to 1 unit in an electricity bill? Watt(W) is unit of power and 1000 watts equals 1 Kilowatt (Kw) .Kilowatt hour (Kwh) is the unit of energy consumed which the unit charged in the electricity bill. If you are using 1 Kw power ( sum of all loads including lights/fan TV etc., if switched on and working at the same time) for one hr your consumption will be 1 Unit.

Electrical Demand Another related term is kiloWatt hours, which is a measurement of total electricity used for a period of time. A 1000 watt electrical load used for one hour consumes one kiloWatt hour (kWh). Electrical Utilities typically charge commercial and industrial customers for both consumption (kWh) and Demand (kWd or kVa).

- Energy can be measured in Joules *, or in Kilowatt-hours (KWh), and in various other energy units, like the way amounts of money can be measured in pounds, dollars, euros, etc. The type of concept of a battery full of energy is like a bucket full of water, or like a bag full of cash. POWER is a rate of flow of energy. It is energy per second, so its standard unit is the Joule per Second (which is the same as Watts). It can also be measured in kilowatts, megawatts, etc. Using the money analogy, power is like income or spending power, a rate at which you can transfer money.

What is a kWh? kW and kWh explained A kilowatt hour (kWh) is a measure of how much energy you’re using. It doesn’t mean the number of kilowatts you’re using per hour. So if you switched on a 100 watt light bulb, it would take 10 hours to rack up 1 kWh of energy. Or a 2,000 watt appliance would use 1 kWh in just half an hour.
