KWh is the unit of measurement that quantifies how much energy is used over a period of time, calculated by multiplying the kW of energy consumption by the total number of hours the lighting has been operated.ġ0 bulbs X 100W = 1,000W or 1kW of lightingġ0 hours of daily use X 30 days in the month = 300 hours of useġkW X 300 hours of use = 300kWh of energy consumptionĪ significant portion of your electricity bill is based on your energy consumption in kilowatt-hours. Insert milliamp hour (mAh) and voltage (V) and click on Calculate to obtain Watt hours (Wh). Your energy usage depends on how long you keep everything on. Ten 100W light bulbs is equal 1kW of energy usage. To convert a measurement in watt-hours to a measurement in kilowatt-hours, divide the energy by the following conversion ratio: 1,000 watt-hours/kilowatt-hour. To convert W to kW, divide the total wattage by 1,000. Watts (W) to kilowatts (kW): 1kW is equal to 1,000W. Energy (E) in kilowatt-hours (kWh) is equal to the power (P) in watts (W) multiplied by the number. A Kilowatt-hour is a unit of energy and its. Kilowatts are a measure of how much energy something consumes. To calculate energy consumption follow this simple formula. Enter the power in watts (W), time period in hours (h), then press the Calculate button to get the result in kilowatt-hours (kWh). Wikipedia page for Kilowatt-hour (watt-hour redirected to kWh). Lumens are the measure of how much light the bulb produces.

Both watts and kilowatts are SI units of power and are the most common units of power used. Watts are a measure of how much energy the light bulb will use as it produces light. One kilowatt (kW) is equal to 1,000 watts. Light bulbs are rated in watts to indicate how much energy they consume.Ī 60W incandescent bulb typically gives off around 650-800 lumens. Next, lets look at an example showing the work and calculations that are involved in converting from watts to kilowatts (W to kW). Unit of electrical power equal to 1 joule per second. The difference between watts (W), kilowatts (kW), and kilowatt-hours (kWh).
