1 cm = 10 mm
So 1.9 cm = 19 mm, and 13 mm = 1.3 cm. This means that 13 mm is shorter than 1.9 cm because 13 mm (1.3 cm) is shorter than 19 mm (1.9 cm).
13 mm is shorter.
1.9 cm = 19.0 mm 19 cm = 190 mm So 1.9 cm is shorter then 190 mm cm means centimeter mm means miliimeter
19.7 cm. 191 mm can be converted to 19.1 cm, which is shorter.
13 cm is equal to 130 mm.
1 cm = 10 mm, so 13 cm = 130 mm.
There are 10mm to 1cm so there are 130mm to 13cm
1cm = 10mm 175.6 mm = 17.56 cm
Which is the shorter length, 175.6 mm or 38.4 cm
19 mm. To convert cm to mm multiply by 10, to convert mm to cm divide by 10.
19 mm is more precise than 2 cm because it is a smaller unit of measurement. There are 10 mm in 1 cm, so 19 mm is more specific than 2 cm.
The problem here is that you don't know what cm and mm are.cm is centimetre, which is one-hundredth of a metremm is millimetre, which is one-thousandth of a metreThe world outside the USA spells metre differently from, for example, a parking meter, because they are completely different. Americans spell metre "meter" good luck with that.
Convert cm into mm or mm into cm: 3.6cm - 1.9cm = 1.7cm, or 36mm - 19mm = 17mm
