CD case is in mm ( millimeter)
The width of a CD case is five inches. The length, in case you are wondering, is 4.75 inches. This is the length and width of an average CD case. Some might be a little different, but this is the one most commonly used.
It depends on what characteristic of the CD case is being measured: its mass, linear dimensions, volume, transparency to light (or other electromagnetic radiation), its brittleness, etc.
I think the question should be: mm in cm? In which case, there are 10 millimetres in 1 centimetre.
You will be better served if you learn to do unit conversions in general. All it takes is to multiply your starting value by a fraction formed by the unit conversion. In this case, the conversion is that 1 cm = 10 mm. You can make two different fractions: 1 cm/10 mm = 1 or 10 mm/1 cm = 1. Multiply by the form that will divide out the unit you are trying to eliminate.In this case:9 mm x (1cm/10 mm) = 9x1/10 cm = 9/10 cm = 0.9 cmThis type of operation is very easy and very routine.
1 cm = 10 mm 8 cm = 80 mm 80 cm = 800 mm 86 cm = 860 mm 86.3 cm = 863 mm 86.36 cm = 863.6 mm
I presume you mean cm as in centimeters (there being no C prefix in SI units): 100 cm = 1 m ⇒ 48725 cm = 48725 ÷ 100 m = 487.25 m I may seem picky over Cm and cm, but consider: millimeters are mm; 1000 mm = 1 m megameters are Mm; 1000000 m = 1 Mm ⇒ 1 Mm = 1000000000 mm = 109 mm ⇒ 1 mm = 0.000000001 Mm = 10-9 Mm A difference of a factor of a billion made by the prefix being upper case (M) or lower case (m)! It is important to write units in the correct abbreviation so that others read what you mean.
1 cm = 10 mm 2 cm = 20 mm . . . 9 cm = 90 mm 10 cm = 100 mm 20 cm = 200 mm 30 cm = 300 mm
To change mm to cm you simply just multiply your number with 10. In this case the answer will be 5cm
1 cm = 10 mm → 3.5 cm = 3.5 × 10 mm = 35 mm
1 cm = 10 mm 2 cm = 20 mm . . 10 cm = 100 mm . . 15 cm = 150 mm
10 mm = 1 cm 100 mm = 10 cm 1,000 mm = 100 cm 3,000 mm = 300 cm 3,500 mm = 350 cm
10 mm = 1 cm 20 mm = 2 cm 200 mm = 20 cm 240 mm = 24 cm 244 mm = 24.4 cm
