Conversion 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 standard units, and vice versa
- among different scientific notation (e.g., kilo-, mega-, giga-, micro-)
- from parts per million (PPM) to lower explosive limit (LEL) to percent gas, and vice versa
- BTUs to therms.
