Calculation of Machine’s Electricity Consumption for Costing

Historically, horsepower was the first power unit emerged and widely used around the world. In the middle ages, a horse was one of the most important elements of almost every household, that is why starting from the 18th century, with the development of first steam engines, a horsepower was chosen as a great comparative unit of power.

In our times, there are a few types of horsepower are used. In those countries where the Imperial system is practiced, mechanical or imperial horsepower is used, which is approximately equal to 745.7 watts. Electrical horsepower is a unit that is equivalent to 746 watts. It is usually used for rating electric motors and engines. There is also metric horsepower which has been used in Europe since the beginning of the 19th century. It is equivalent to roughly 735.5 watts.

Horsepower to Kilowatts Calculation

1 hp = 33,000 ft•lbf / minutes 
1 hp = 33,000 ft•lbf / 60 seconds 
1 hp = 550 x 0.3048 x 0.453592376 m•kgf/s
1 hp = 76.04022591264 kgf•m/s 
applying gravity constant
1 hp = 745.699872 N•m/s 
by definition 
1 ft = 0.3048 m 
1 lb = 0.453592376 kg
we need kilowatts
1 kW = 1000 W
 
1 hp = 745.699872 N•m/s • (1/1000)
1 hp = 0.745699872 kW

once you worked out  your machine’s KW you can easily calculate per day consumption of electricity (KWh*no. of hours machine run time per shift * no of shifts per day*no days factory run in a month)*Electricity charges per KWH (unit)

you will get your machine’s electricity consumption cost which will be very helpful in determination of costing of products.
