Meters to cm (m to cm)

One meter is exactly 100 centimeters, by the meaning of the prefix: centi is a hundredth. Nothing is measured and nothing could be revised.

Worked through: 1.75 m x 100 = 175 cm.

Going the other way, one centimeter is 0.01 meters.

For mental arithmetic: Move the decimal point two places right. 1.75 m is 175 cm.

Worth knowing that the centimeter is the odd one out of the metric length units. The SI prefers steps of a thousand (millimeter, meter, kilometer), and engineering and construction drawings follow it, dimensioning everything in millimeters. The centimeter survives in clothing, body measurements and school rulers, which is why a height is 175 cm on a medical form and a door is 2040 on a builder's plan. The conversion goes wrong with decimals that have a zero after the point: 1.08 m is 108 cm, and reading it as 18 cm, or writing 1.8 m for 108 cm, is a common transcription slip on forms that ask for one unit and receive the other.

Precision is worth matching to the input. A measurement given as 0.25 m carries one or two significant figures, and reporting its conversion to six implies a precision the original never had.
