very hard to convert, about 2.5-3.5hp per 100 cc in mowers
9 HP
You can't. 123 cc is a volume, horse power is power. If you know the output of a 123 cc engine, either (i) you already know its horsepower, or (ii) you convert kilowatts to horsepower by hp = kw/0.746.
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.
You don't. cc is the size of the engine. It cannot specify the h.p. which is variable.

No.

Displacement doesn't directly equivocate to horsepower.
See this link for a complete table. The ratio is not constant because the relationship depends on other factors. http://www.simetric.co.uk/si_cc2hp.htm how munch hp in a208 cc snowblower
