Conversions<\/h2>\n
An amp is the measure of the amount of current or electrical energy that is passing through an electric line, whereas a Watt is the unit for measuring electrical power. It is calculated by multiplying the voltage (V) and the current (amps) being used.<\/p>\n
Here\u2019s the formula for calculating amps to watts:<\/p>\n
Wattage = Amps \u00d7 Voltage<\/p>\n
For example, if you have a 120V device with a 20 Amp label, that\u2019s equivalent to a wattage of 2400. In equation form, that is: 20A \u00d7 120V = 2400W<\/p>\n
Formula for Converting Watts Into Kilowatts:<\/h3>\n
P(kW) = P(W) \/ 1,000
\n(1 kilowatt = 1000 watts)<\/p>\n
For example, if you wanted to convert your 1500W dishwasher to kilowatts, you would do the following calculation:<\/p>\n
P(kW) = 1,500W \/ 1,000 = 1.5kW<\/p>\n
Formula to Convert Kilowatts to Megawatts:<\/h3>\n
P(MW) = P(kW) \/ 1,000<\/p>\n
The power in Megawatts is equal to the power in Kilowatts divided by 1000.<\/p>\n
This formula also means that if you would like to convert watts to megawatts, you have to add three more zeros to your equation. The power in megawatts P(MW) can be found by dividing the power in watts P(W) by 1,000,000.<\/p>\n
Here\u2019s the Formula to Convert Watts to Megawatts:<\/h3>\n
P(MW) = P(W) \/ 1,000,000<\/p>\n
For example, if you convert a 100-watt light bulb to megawatts, you will do the following calculation:<\/p>\n
P(MW) = 100W \/ 1,000,000 = 0.000100MW<\/p>\n
