In geometric measurements, length is the langest dimension o an object. In ither contexts "length" is the measurt dimension o an object. For example it is possible tae cut a length o a wire which is shorter than wire thickness.
Length mey be distinguished frae hicht, which is vertical extent, an width or breadth, which are the distance frae side tae side, measurin athort the object at richt angles tae the length. Length is a measur o ane dimension, whauras aurie is a measur o twa dimensions (length squared) and volume is a measur o three dimensions (length cubed). In maist seestems o measurement, the unit o length is a fundamental unit, frae which ither units are defined.
