Just so you know, most of these measurements are not metric. Inches, Miles, Feet, Yards, Stones, Pounds, Gallons, Quarts, and Acres are all imperial measurements. Metric is things like meters, litres, and grams (all with the appropriate prefixes, kilo, milli, centi, deci). Considering this is a Metric conversion quiz, I would assume that means either Metric to Metric or Imperial to Metric conversions.
