Engine CC to Horsepower

Calculator small engine
cubic centimeters (CC)
to horsepower (HP).

Engine CC to HP

Many small devices use the
small four cycle engine,
to power them, such as
lawnmowers, snow blowers,
de-thatchers, and roto-tillers,
standby generators, pressure
washers, and utility engines.

Small engines are rated
according to cubic centimeter

The horse power of the
engine can be calculated by
dividing CC by 32.5, this
gives an approximate working
output hp over a wide range of
engines designs.

Calculations are based on
a RPM of 3600 with air
cleaner and muffle in place.

Calculator Instruction

Enter Four Cycle Engine
Rated CC.


A four cycle engine rated at
123 CC will produce
approximately 4 horsepower.

A four cycle engine produces
power only on two cycles of
the four revolutions.

This calculator is based on,
every 32.5 cubic centimeters
produces one horsepower.

Horsepower will vary
somewhat due to compression
differences and engine
physical construction.

This calculator gives an
approximate hp over a broad
range of 4 cycle small
