Watts Amps Volts Calculator

The Watts Amps Volts Calculator for Android is the essential electrical power tool for electricians, engineers, students, and DIY enthusiasts. Quickly convert and calculate Watts, Amps, Volts, kW, and Power Factor — no more manual formula lookups. Watts Amps Volts is an advanced Ohm's Law calculator for AC Single-Phase, AC Three-Phase, and DC electrical calculations. Easy to use electrical power calculator for converting and calculating to and from Watts, Amps, Volts, kW or Power Factor (PF) AC and DC. Electrical calculations include AC 1-phase (single-phase), AC 3-phase (three-phase) and DC electrical calculations. AC Single-Phase Calculations: ✓ Calculate Watts. ✓ Calculate Amps. ✓ Calculate Volts. AC Three-Phase Calculations: ✓ Calculate kW. ✓ Calculate Amps. ✓ Calculate Volts. ✓ Power Factor (PF). DC Calculations: ✓ Calculate Watts. ✓ Calculate Amps. ✓ Calculate Volts. Electrical units are measured in the following: Current (I) = Amps. Power (P) = Watts (or kW). Volts (V) = Voltage. Ohms Law Formula - Single Phase: To calculate Voltage (V): V = I x R To calculate Amps (I): I = V ÷ R To calculate Resistance (R): R = V ÷ I Simple, fast, and accurate — the electrical calculator you'll reach for every day.
