Here is a formula I have found on the net to calculate horsepower...feet/lbs. torque x rpm divided by 5252...this will give you the horsepower for your snowblower...ex: 21feet/lbs. of torque x 3600 rpm divided by 5252 gives me 14.39 horsepower...This is what comes up for my Ariens Pro 28 snowblower with a 420 cc Briggs engine...

The reason why they switched to Litres is simply because of the metric system in Canada and to be compatible with the rest of the World. In the USA it is still the imperial inch system. Cubic Inch is for the Imperial system and Litres or cubic metres for metric. This defines the displacement of the engine. Horsepower is part of the inch system and it still used today in the auto industry combined with other metric values/specifications. It gets kind of complicated for someone who doesn't know both systems...ex: my son goes to a Canadian High School and they are teaching him only the Metric system and no Imperial inch system at all....However, they still speak about Horsepower which is part of the inch system. Instead they should be speaking about Kilowatt power to be more accurate and standard with the Metric system. Actually, they should be teaching both systems as it is used daily in Canada. Especially in the manufacturing world everything is converted to the Inch system before processing. I personnally prefer the Inch system over Metric as it is the system of the Universe and not made by mankind...

The Marketing and sales people Lie about the Horsepower, and use it to sell whatever they have on hand. So the actual(usually in Cibic Centimeters CC, for short) Displacement is all you can get which still doesn't tell you how powerful any given engine is. If Consumer Reports would just accurately and objectively measure and publish the horsepower of the engines on the machines they test, they'd force the manufacturers to publish actual and not fictitious Horsepoer meausrements. This is just one issue, and why buying power equipment is an exercise in evaluating what the seller doesn't want you to know. If you get actual accurate HP numbers, then try getting the size of the friction whaeel and drive plate that make the snowblower move. Good luck finding out that speciafication, or even just how much the machine weighs. Like I said they don't want you to know . . . . A Lot !
