Definition of Unit conversions
Check what you remember
Read the wording for your board, then hide it and explain Unit conversions in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
Charge is often expressed in coulombs, and units such as millicoulombs (1 mC = 1 × 10⁻³ C) or microcoulombs (1 μC = 1 × 10⁻⁶ C) must be converted when necessary.
