A postage stamp: millimetres.
the unit of length used in measuring long objects are yards and feet and inches.
The metre.
I would expect it would be centremetres.
By unit of length and distance and conversion ,we can say that a centimeter ruler used for measuring the length,width of the objects in centimeters ,etc.
Liquid mass is measured in grams/kilograms. A liquid cannot have a length.
the unit of length used in measuring long objects are yards and feet and inches.
Length
By unit of length and distance and conversion ,we can say that the unit used for measuring length is m,cm,km,hm,dm,etc.
The metre.
kilometer
Units of length, such as mm, are used for this.
miles
It depends on what you are measuring but feet and inches are mostly used.
When I took physics my teacher always had us use meters when measuring length because that was the unit that all the equations used. If we found a length of only a few centimeters she made us change it to a decimal number with meters as the unit. (ex. 75cm = 0.75m)
I would expect it would be centremetres.
A cubic centimetre (cm3) is a unit of volume (V).
By unit of length and distance and conversion ,we can say that a centimeter ruler used for measuring the length,width of the objects in centimeters ,etc.
