Ohms Law Calculator

Please provide any 2 values and click "Calculate" to get the other values in the ohm's law equations V = I × R and P = V × I

Voltage (V): kilovolts [kV] volts [V] millivolts [mV] Current (I): amperes [A] milliamperes [mA] Resistance (R): ohms [Ω] kilohms [kΩ] megohms [MΩ] Power (P): watts [W] kilowatts [kW] megawatts [MW] horsepowers BTU/h
