Title: Interpret units of measure.
Course: Power Generation Design and Function (20904-II) > Section: Performing Test, Calibrations, and Measurements

Interpretation should include the use of unit conversion charts and formulas (e.g., Watt’s law, Ohm’s law, ideal gas law) to convert

- metric to U.S. customary standard units, and vice versa
- scientific notation (e.g., kilo-, mega-, giga-, micro-)
- parts per million (ppm), lower explosive limit (LEL), and percent gas concentration
- British thermal units (BTUs) to therms.

Process/Skill Questions:

- Why are scientific notation prefixes used in energy situations?
- What is a therm?
- Why is natural gas measured in dekatherms (dth)?
