To calculate amps to watts, you can use the formula: watts = amps x volts. How many amps are in 20 amps? At 120V, 20 amps is equivalent to 2400 watts. At 240V, it would be equivalent to 4800 watts. The wattage will vary depending on the voltage of the circuit. The basic formula ...
The Watts Equation in Mechanics You can use either of the following equations to calculate power in watts, provided all quantities are expressed in in MKS (meters, kilograms, seconds) metric units. P=F×v P=Wt If you do your measurements on the CGS (centimeters, grams, seconds) system, f...
Watts is a unit of energy that measures power conversion. If you can calculate the "watts per square foot," it will permit you to estimate the average electric power usage for things such as lighting, air-conditioning and other electric equipment in a building or a room. It's also a way...
Find the number of volts on the battery source. For example, assume you have a 12-volt battery. Divide 30 watts by the amount of volts in the circuit. In the example, 30 watts divided by 12-volts equals 2.5
You can calculate volts from kilowatts andamps, but you can't convert kilowatts to volts since kilowatts and volts units do not measure the same quantity. DC kW to volts calculation formula The voltageVin volts is equal to 1000 times the powerPin kilowatts, divided by the currentIin amps...

How do we calculate the energy used in electrical appliances?The energy used by electrical appliances can be calculated using the formula: E = P × t, where E is the energy in watt-hours (Wh) or kilowatt-hours (kWh), P is the power rating of the appliance in watts (W) or k...
How do you calculate power-to-weight ratio? To determine your PWR, divide your bodyweight in pounds by 2.2 to convert it to kilograms, then divide your functional threshold power (FTP) by your weight in kilograms. Average FTP / [bodyweight in lbs/2.2] = PWR (watts/kg) ...

electrical bill comes. The energy does produce light, but you can't convert lumens to watts and back again because not all of the input energy goes into the production of light. The best you can do is form a ratio of lumens to watts, which is the luminous efficiency of the light bulb...
