13.1 Selected Conventional Metric Units
13.2 Selected International System
Units
The units of measurement used throughout the text are the conventional metric units, supplemented on a few occasions by the British units. However, for the convenience of the readers who may have familiar with the new International System of Units their conversion factors into the conventional units, and vice-versa, are given bellow for all the units that are not identical in the systems and that have been used in the text.
Power: | 1 horsepower (hp) = 0.7457 kW |
Specific energy: | 1 kilocalorie per kilogramme (kcal/kg) = 4.187 kJ/kg |
Heat flow rate: | 1 kilocalorie per hour (kcal/h) = 1.163 W 1 British thermal unit per hour (Btu/h) = 0.2931 W |
Specific heat capacity, mass basis: | 1 kilocalorie per kilogramme, degree Celsius (kcal/kg deg C) = 4.187 J/g deg C |
