If you were looking at something small, it is more meaningful to say this is 20 microns long, instead of 0.02mm. When you talk about decimal places, it is harder to grasp the figure as quickly as people often working with microns grasp the relevance of 20micron. Such samples include fiber size, transsectional areas taken for cell viewing through a light microscope (using a microtome, you get a nice cut), etc.
You could use either inches or centimeters to measure the width of a sheet of paper.
To convert micrometres (µm) to millimetres (mm) in biology, you divide the number of micrometres by 1,000, since 1 millimetre is equal to 1,000 micrometres. For example, if you have 500 µm, the conversion to millimetres would be 500 µm ÷ 1,000 = 0.5 mm. This conversion is useful for accurately measuring and comparing small biological structures.
Millimetres to 1 decimal place (or micrometres rounded to the nearest 100).
Millimetres
If I was you i would use millimetres or centimetres.
I would use centimetres and millimetres
Millimetres
Millimetres.
Millimetres.
Measurement is different objects you can measure for example you could measure a road. What would you use? millimetres, centimetres, metres or kilometres? I would choose kilometres because if you used millimetres it would take a long time to measure. Measurement is just mostly about measuring but you have to use all the skills you have like Addition, Subtraction, Multiplication and Division. Things that go into measurement that I know are: Area Perimeter Volume and Angles
A calculator would be between 100 and 150 millimetres.
Either inches or millimetres Or centimetres.
