usually kilometers
The distance between towns is commonly measured in miles or kilometers.
A kilometre would be the most appropriate unit.
The best unit of measurement for the measuring the distance between two towns would be miles. You could also use kilometers if you want, but anything smaller than miles or kilometers would make getting the correct measurement difficult.
A calculator would be between 100 and 150 millimetres.
The length of an aeroplane would be measured in metres.
Meters should be used to measure the length of a tennis court in metric units.
I would use centimetres.
Length->metersVolume->LitersMass->grams
No, a foot is not a metric measurement. Metric measurements of length would include millimeter, centimeter, meter, and kilometer.
There is no such measurement. There is either metric measurement or not. Do you mean "fractions" of inches?
