I would use a millimetre, but since the SI system allows simple conversions for multiples of ten and factors of ten, that is simply a presentational detail.
Centimetres.
I would use centimetres.
I would use centimetres and millimetres
centimetres lol
Millimetres would be better, as centimetres would be too long for a short ladybird (UK name).
In the English system, probably inches. In the metric system, probably centimetres.
Feet and inches or metres and centimetres.
The best option is metres, centimetres and millimetres
No. You would use different units of measurement. You would measure the size (circumference) of your waist (for trousers) in centimetres. You would not measure the distance to the moon in centimetres!
the basic measure of length used to measure the thckness of a pin or leaf is in millimeter
Feet and inches, or metre and centimetres.
Metre to measure its length. Possibly centimetres to measure its height if a garden fence but metres if a security fence.
