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)?
