[X] cm = 0.1 × [Y] mm

where [X] is the result in cm and [Y] is the amount of mm we want to convert

where [X] is the result in cm and [Y] is the amount of mm we want to convert

210 mm to cm conversion result above is displayed in three different forms: as a decimal (which could be rounded), in scientific notation (scientific form, standard index form or standard form in the United Kingdom) and as a fraction (exact result). Every display form has its own advantages and in different situations particular form is more convenient than another. For example usage of scientific notation when working with big numbers is recommended due to easier reading and comprehension. Usage of fractions is recommended when more precision is needed.

If we want to calculate how many Centimeters are 210 Millimeters we have to multiply 210 by 1 and divide the product by 10. So for 210 we have: (210 × 1) ÷ 10 = 210 ÷ 10 = 21 Centimeters

So finally 210 mm = 21 cm
