To convert cubic centimeters (cc) to horsepower (hp), you can use the rough estimate that 1 horsepower is produced by approximately 15-17 cc of engine displacement, depending on various factors. Therefore, a 660 cc engine typically produces about 39 to 44 horsepower. However, this is a general estimate and actual horsepower can vary based on engine design, efficiency, and tuning.

Displacement doesn't directly equivocate to horsepower.
the cubic centimeters of 6.5 horse power is 175 cc
8.0 horse power - 125 cc
It's about 5.5hp
10 horse power
50 horse power
you can convert cubic inches to cc's but not horse power. an engine with say 65 cc's can have different amounts of horse power depending on carberation, pistons, valves etc. etc. etc. but my 65 cc engine does have 1.89 hp if that helps.
148 cc is 3.5
very hard to convert, about 2.5-3.5hp per 100 cc in mowers
CC can vary between 15 and 17 cc per horse power, so a 3 horsepower motor has a cc of about 48 cc.
