To quickly assess the difficulty of the text, read a short excerpt:
It is desirable, both on theoretical and practical grounds, that the horsepower represent an absolute and in- variable amount of power, and to do so it must equal a definite number of watts. So defined, its equivalent in local foot-pounds per second varies with latitude and altitude in a determinate manner. The definition of the pound as a unit of force is intimately involved, and it is, accordingly, treated in the following pages. The horsepower defined as 746 watts is equivalent to 550 foot-p...ounds per second at 50 latitude, very near where the original experiments were made by James Watt to establish the value of the horsepower. The "continental horsepower, " which is used in Germany and France and generally on the continent of Europe, is equal to 736 watts, or 75 kilogram-meters per second at Berlin. It is thus more than i per cent different from the horsepower as used in the United States and Great Britain. Modern practice is tending toward the more general use of the kilowatt and the disuse of the horsepower.
