OK, a question ....

Angela sponsors two horses at the sanctuary , one is a shetland pony called Ben and one is a mahoosive shire horse called Bonny ..... so it got me thinking ....

As we all know, cars are measured in horsepower , but one of Bens horsepower is a lot less than one of Bonnys horsepower ...

So, what it the benchmark that cars are judged on ?

Horsepower - Common unit of power, the rate at which work is done.

In the English system, one horsepower equals 33,000 foot-pounds of work per minute — that is, the power necessary to lift a total of 33,000 lbs a distance of one foot in one minute.

This value was adopted by James Watt in the late 18th century after experiments with strong dray horses and is actually about 50% more than the rate an average horse can sustain for a working day.

The electrical equivalent of one horsepower is 746 watts in the International System of Units

The heat equivalent is 2,545 BTU per hour.

The metric horsepower equals 4,500 kg-m per minute (32,549 foot-pounds per minute), or 0.9863 horsepower.
