Measurement precision
Every measuring tool reads only down to its smallest marking: a ruler marked in centimetres has a precision of 1 cm, one marked in millimetres 1 mm, a kitchen scale showing tenths of a gram 0.1 g. A result is written to the tool's precision, never finer, rounding to the nearer mark when an edge falls between two, and the precision is reported with it. How careful the measurer is matters too: start at zero, look straight on.

You can find a tool's precision from its markings, report a measurement to that precision by reading the nearer mark, and name common mistakes of the person measuring.
