A
V

HORSEPOWER

4.92 HP

WATTS

4,080 W

FORMULA

HP=(Iร—Vร—PFร—Eff)/746

1 HP

= 746 watts

๐Ÿ’ก How to Convert Amps to HP

Formula

HP = (I ร— V ร— PF ร— Eff) / 746

Where 1 HP = 746 watts
Example: 20A at 240V, PF=0.85, Eff=90% โ†’ HP = (20 ร— 240 ร— 0.85 ร— 0.9) / 746 = 4.93 HP
20A ร— 240V ร— 0.85 PF ร— 0.9 Eff รท 746 = 4.93 HP.
