That depends on the individual desk, doesn't it - but you don't mix units quite like that in the metric system.
You would quote the dimensions of a piece of furniture in either metres to 2 or 3 decimal places, or whole numbers of millimetres. E.g. 1.25m OR 1255mm. Not both.
Shops, and UK schools, tend to use the centimetre although it is NOT a "preferred" division of the metre, and then you'd measure a desk in only cm, not m and cm.
meters
Inches or centimeters, depending on where you live.
Centimeters are a unit of measure of length (for example, how long a pencil is). Kilograms are a unit of measure of mass (for example, how many kilograms of mass are contained in a desk). So, you cannot say how many centimeters are in a kilogram. If you are interested in length: There are 100,000 centimeters in 1 kilometer. If you are interested in mass: There are 100,000 centigrams in 1 kilogram.
Typically, you measure a desk height with feet and a desk width with feet also. But, it depends on the size.
It would be feet
Meters, centimeters, or millimeters. Take your pick.
meters
You would probably measure a keyboard in centimeters (cm).
The SI unit used to measure the height of a desk is meters (m).
I prefer to use millimetres or if the measurement is over 1 metre I would say 1.25 or 12 hundred and 50. So a desk might be 900x500 x750 high
It depends on which school desk. But mostly, it is measured in meters or centimeters.
12meters
It depends on the width of the desk. You could use centimeters or meters.
Well, darling, you would use good old-fashioned inches or centimeters to measure a desk. None of that fancy stuff, just whip out a ruler and get to work. Unless you want to get really wild and measure it in bananas, but I wouldn't recommend that for accuracy's sake.
because for very small people like dwarfs you could not use a human metre. So human use centimeters to measure
Inches or centimeters, depending on where you live.
centimeters or both meter & centimeter
