Subject: Unit converters

A meter-based plan may describe a room, a roll of fabric or a length of cable. Convert each dimension before comparing labels, and keep lengths separate from floor areas. A measurement of 1.75 m includes three quarters of a meter, rather than 75 extra meters.

One metre is exactly 100 centimeters, so 1.75 m is 175 cm. To convert meters to cm, multiply by 100; to convert back, multiply by 0.01.

The centimetre is one hundredth of a metre, the SI base unit of length. Because both units are defined exactly, the factor above is exact and the results here carry no conversion error.

## Inputs

- **Meters (m)**

## Results

- Centimeters (cm) — main result
- Conversion
- 1 cm in meters (m)

## Formula

$$
\text{centimeters} = \text{meters} \times 100
$$

## Worked examples

### 1.75 m to cm

- Meters (m): 1.75 m
- **Centimeters: 175 cm**
- Checked against: Exact-fraction computation from the legal unit definitions (scripts/gen-pairs.py, Python fractions)

### 1 m to cm

- Meters (m): 1 m
- **Centimeters: 100 cm**
- Checked against: Exact-fraction computation from the legal unit definitions (scripts/gen-pairs.py, Python fractions)

### 5 m to cm

- Meters (m): 5 m
- **Centimeters: 500 cm**
- Checked against: Exact-fraction computation from the legal unit definitions (scripts/gen-pairs.py, Python fractions)

## Questions

### How do I mark 1.75 meters on a centimeter tape?

Use the 175 cm mark: 1.75 multiplied by 100 is 175. If the source is a room plan, this converts one length only. An area in square meters needs a separate squared-unit conversion.

### How many centimeters are in a metre?

One metre is exactly 100 centimeters. The centimetre is one hundredth of a metre, the SI base unit of length.

### How do you convert meters to cm?

Multiply the number of meters by 100. For example, 1.75 m × 100 = 175 cm. To go the other way, divide by 100.

### How accurate is the meters to centimeters converter?

Accuracy depends on your inputs and the method's assumptions. Decimal arithmetic uses 50 significant digits, but estimates, numerical methods and source data can be less precise; the displayed rounding does not remove those limits. It is checked against 3 worked examples whose answers come from independent sources; for example, “1.75 m to cm” is checked against Exact-fraction computation from the legal unit definitions (scripts/gen-pairs.py, Python fractions).
