Amps to Watts Calculator Online



The formula for calculating Amps to Watts for DC is

Amps to Watts (Current Type=DC) = 1000 ×
I(A) × V(V) / 1000


Example of Calculations for current type DC:

Current (amps): 23

Voltage (volts): 4

Amps to Watts (Current Type=DC) = 1000 ×
23 × 4 / 1000
= 92 W


The formula for calculating Amps to Watts for AC - Single Phase is

Amps to Watts (Current Type = AC - Single Phase) = 1000 ×
PF × I(A) × V(V) / 1000


Example of Calculations for current type AC - Single Phase:

Current (amps): 23

Voltage (volts): 4

Power Factor (PF): 0.5 (must lie between 0-1)

Amps to Watts (Current Type = AC - Single Phase) = 1000 ×
0.5 × 23 × 4 / 1000
= 46 W


The formula for calculating Amps to Watts for AC - Three Phase (voltage type = Line to line voltage) is

Amps to Watts (Current Type = AC - Three Phase) = 1000 ×
√3 × PF × I(A) × VL-L(V) / 1000


Example of Calculations for current type AC - Three Phase:

Current (amps): 23

Voltage (volts): 4

Power Factor (PF): 0.5 (must lie between 0-1)

Voltage Type: Line to line voltage

Amps to Watts (Current Type = AC - Three Phase) = 1000 ×
√3 × 0.5 × 23 × 4 / 1000
= 79.674337148 W


The formula for calculating Amps to Watts for AC - Three Phase (voltage type = Line to neutral voltage) is

Amps to Watts (Current Type = AC - Three Phase) = 1000 ×
3 × PF × I(A) × VL-L(V) / 1000


Example of Calculations for current type AC - Three Phase:

Current (amps): 23

Voltage (volts): 4

Power Factor (PF): 0.5 (must lie between 0-1)

Voltage Type: Line to neutral voltage

Amps to Watts (Current Type = AC - Three Phase) = 1000 ×
3 × 0.5 × 23 × 4 / 1000
= 138 W
