Units explained
Meter
The meter is the SI base unit of length. Since 2019, the meter has been defined by fixing the numerical value of the speed of light in vacuum to exactly 299,792,458 meters per second. Every other SI length unit derives from the meter.
The meter was originally defined in 1793 by the French Academy of Sciences as one ten-millionth of the distance from the equator to the North Pole along a meridian through Paris. It has been redefined multiple times — by physical prototype, then by atomic transitions, and finally in 2019 by fundamental physical constants.
The meter is the international standard for length in science, engineering, construction, athletics, and everyday measurement in metric countries. It underpins definitions of area (m²), volume (m³), and most derived SI units.
Established 1793 in France; ratified internationally via the Metre Convention 1875; redefined in 1960, 1983, and most recently 2019 when the SI redefinition fixed it to the speed of light.
Centimeter
A centimeter is a metric unit of length equal to one hundredth of a meter (1/100 m). It is one of the most commonly used SI sub-units in daily life, especially for measuring small objects, body dimensions, paper sizes, and short distances.
The centimeter emerged from the French metric system established by the French Academy of Sciences in 1793. The metric system introduced decimal-based prefixes (milli-, centi-, deci-, deca-, hecto-, kilo-) to create proportional sub-units of the meter.
Centimeters are the standard unit for everyday measurement in nearly every country outside the United States. They are used for body height, clothing sizes, rainfall, paper formats (A4 is 21 × 29.7 cm), screen dimensions, and most consumer product specifications.
Developed in France during the late 18th century as part of the metric system designed by the French Academy of Sciences. Formally adopted in France in 1795 and ratified internationally through the Metre Convention signed in Paris in 1875.
Meter to Centimeter conversion formula
The relationship between meters and centimeters:
To convert meters to centimeters, multiply the value in meters by 100. To reverse, multiply centimeters by 0.01.

Step-by-step: convert meters to centimeters
- Write down the value in meters (m).
- Multiply that value by the factor 100.
- The product is the equivalent value in centimeters (cm).
- To reverse, multiply the centimeter value by 0.01.
Worked examples
Example 1 — Convert 1 m to cm:
1 × 100 = 100 cm
Example 2 — Convert 100 m to cm:
100 × 100 = 10000 cm
Real-world example — Architectural drawing precision
Architectural plans usually note overall room dimensions in meters but specify hardware (door hinges, plug positions, baseboard heights) in centimeters. Converting 1 m to 100 cm is the routine arithmetic of reading any standard architectural drawing.
1 m × 100 = 100 cm
Real-world example — Translating height into metric forms
You record your height as 1.8 m on a passport application, but the same form's printout shows centimeters on the medical examination certificate. Moving 1.8 m to 180 cm is the everyday conversion every metric-using country requires for forms that mix the two scales.
1.8 m × 100 = 180 cm
Real-world example — Furniture and rug dimensioning
A 2.4-m sofa fits perfectly against a 240-cm wall. Furniture stores frequently list big items in meters but carpets and rugs in centimeters — converting 2.4 m to 240 cm keeps your floor-plan sketch consistent.
2.4 m × 100 = 240 cm
