Power Converter

Basic Power Definition

P = E / t

Power equals energy divided by time

Example: 3,600 J / 1 s = 3,600 W

Mechanical Power

P = F × v

Force times velocity

Example: 100 N × 2 m/s = 200 W

Electrical Power (DC)

P = V × I

Voltage times current

Example: 120 V × 10 A = 1,200 W

Electrical Power (Resistance)

P = I² × R

Current squared times resistance

Example: 5² A × 10 Ω = 250 W

Rotational Power

P = τ × ω

Torque times angular velocity

Example: 50 N·m × 100 rad/s = 5,000 W

Power from Work

P = W / t

Work divided by time

Example: 1,000 J / 5 s = 200 W

Watts to Kilowatts

kW = W ÷ 1,000

Example: 2,500 W ÷ 1,000 = 2.5 kW

Kilowatts to Watts

W = kW × 1,000

Example: 3 kW × 1,000 = 3,000 W

Horsepower to Watts

W = hp × 745.7

Example: 5 hp × 745.7 = 3,728.5 W

Watts to Horsepower

hp = W × 0.00134102

Example: 1,000 W × 0.00134102 = 1.34 hp

Metric HP to Watts

W = metric hp × 735.5

Example: 10 metric hp × 735.5 = 7,355 W

Megawatts to Kilowatts

kW = MW × 1,000

Example: 5 MW × 1,000 = 5,000 kW
