The tool has no limitations on the number of conversions that can be performed, so you can use it whenever you want.
Examples of energy conversion calculations:
- To convert 2 horsepower to kilowatts, we multiply 2 hp by the equivalence of 11 hp = 0.74570.7457 kW, obtaining 2×0.7457=1.492×0.7457=1.49 kW.
- To transform power from 1,200 watts to BTU/h, we multiply 1,200 W by the equivalence of 11 W = 3.4123.412 BTU/h, obtaining 1,200×3.412=4,094.41,200×3.412=4,094.4 BTU/h.
- Another example would be converting 5 kilowatts to calories per second, we multiply 5,000 W by the equivalence of 11 W = 0.2390.239 cal/s, obtaining 5,000×0.239=1,1955,000×0.239=1,195 cal/s.

Frequently asked questions about converting power units – FAQ
- How do I convert watts to kilowatts?
To convert watts (W) to kilowatts (kW), divide the number of watts by 1000. For example, the calculation would be 5000 W / 1000 = 5 kW.
- How do I convert horsepower (HP) to watts?
One horsepower (HP) is approximately equal to 745.7 watts. To convert HP to W, multiply the number of HP by 745.7. If we have 2 HP, it is 2 x 745.7 = 1491.4 W.
- What is the formula to convert kilowatts to megawatts?
To convert kilowatts (kW) to megawatts (MW), divide the number of kilowatts by 1000. For example, 2000 kW is 2000 / 1000 = 2 MW.
- How do you convert watts to BTU per hour?
One watt is approximately equal to 3.412 BTU/h. To convert watts to BTU/h, multiply the number of watts by 3.412. The calculation would be 1000 W is 1000 * 3.412 = 3412 BTU/h.
- What is a watt and how does it relate to other power units?
A watt (W) is the basic unit of power in the International System of Units, representing 1 joule per second. It relates to other units as follows: 1 kW = 1000 W, or 1 MW = 1,000,000 W.
- How do I convert amps to watts?
You need to know both the voltage (V) and the amperage (A). The formula is W = V * A. For example, if you have 120V and 5A, then the watts would be 120 x 5 = 600 W.
- What is a kilowatt-hour (kWh) and how does it relate to watts?
A kilowatt-hour (kWh) is a unit of energy that represents the energy consumed by a 1 kW device for one hour. To convert watts to kWh, multiply the watts by the hours of use and then divide by 1000. For example, 1000 W for 5 hours is (1000 x 5) / 1000 = 5 kWh.
- What is the difference between power and energy?
Power is the rate at which work is done or energy is consumed (measured in watts), while energy is the capacity to do work (measured in joules or kWh). Power is instantaneous, while energy accumulates over time.
