Meters to Centimeters (m to cm)
There are 100 centimeters in 1 meter. To convert m to cm, multiply the meters by 100 – or simply move the decimal point two places to the right.
To go back from cm to m, divide by 100: 250 cm ÷ 100 = 2.5 m.
| Meters (m) | Centimeters (cm) | Millimeters (mm) |
|---|---|---|
| 0.01 m | 1 cm | 10 mm |
| 0.1 m | 10 cm | 100 mm |

How Long Is a Meter?
One meter is 39.37 inches, or 3.28 feet (3 ft 3.37 in). That makes a meter a little longer than a yard – 1 meter = 1.094 yards, about 3.4 inches more.
The meter is the base unit of length in the metric system (SI). Since 1983 it has been defined by light: the distance light travels in a vacuum in 1/299,792,458 of a second.
How long is 2 meters?
2 meters = 6.56 feet, or 6 ft 6.7 in (78.7 inches). A person who is 2 meters tall is a little shorter than a standard 6 ft 8 in (2.03 m) interior door.

Height Conversion Chart: Feet and Inches to CM and Meters
Heights are usually given in feet and inches in the US and UK, but in centimeters or meters almost everywhere else. To convert, change the height to inches first, then multiply by 2.54.
| Height (ft′in″) | Centimeters | Meters |
|---|---|---|
| 4′10″ | 147.3 cm | 1.47 m |
| 4′11″ | 149.9 cm | 1.50 m |
| 5′0″ | 152.4 cm | 1.52 m |
| 5′1″ | 154.9 cm | 1.55 m |
| 5′2″ | 157.5 cm | 1.57 m |
| 5′3″ | 160.0 cm | 1.60 m |
| 5′4″ | 162.6 cm | 1.63 m |
| 5′5″ | 165.1 cm | 1.65 m |
| 5′6″ | 167.6 cm | 1.68 m |
| 5′7″ | 170.2 cm | 1.70 m |
| 5′8″ | 172.7 cm | 1.73 m |
| 5′9″ | 175.3 cm | 1.75 m |
| 5′10″ | 177.8 cm | 1.78 m |
| 5′11″ | 180.3 cm | 1.80 m |
| 6′0″ | 182.9 cm | 1.83 m |
| 6′1″ | 185.4 cm | 1.85 m |
| 6′2″ | 188.0 cm | 1.88 m |
| 6′3″ | 190.5 cm | 1.91 m |
| 6′4″ | 193.0 cm | 1.93 m |
| 6′5″ | 195.6 cm | 1.96 m |
| 6′6″ | 198.1 cm | 1.98 m |
A short height such as 2′6″ = 76.2 cm = 0.76 m – about the height of a standard dining table or desk.
CM to feet and inches
| Centimeters | Feet + inches | Feet (decimal) |
|---|---|---|
| 150 cm | 4′11″ | 4.92 ft |
| 155 cm | 5′1″ | 5.09 ft |
| 160 cm | 5′3″ | 5.25 ft |
| 165 cm | 5′5″ | 5.41 ft |

| 200 cm | 6′7″ | 6.56 ft |
Metric System Chart: Units of Length
Every metric length unit is a power of 10 of the meter, so converting is just moving the decimal point.
| Unit | Symbol | In meters | Example |
|---|---|---|---|
| Millimeter | mm | 0.001 m | Thickness of a credit card (≈0.76 mm) |
| Centimeter | cm | 0.01 m | Width of a fingernail (≈1 cm) |
| Decimeter | dm | 0.1 m | 10 cm |
| Meter | m | 1 m | Base unit |
| Decameter | dam | 10 m | Rarely used |
| Hectometer | hm | 100 m | Length of a football pitch (≈100 m) |
| Kilometer | km | 1,000 m | About 12 minutes of walking |
1 km = 1,000 m · 1 m = 100 cm · 1 cm = 10 mm
Smaller to bigger unit: divide (mm ÷ 10 = cm). Bigger to smaller unit: multiply (m × 100 = cm).

Metric to Imperial Conversion Chart
Standard conversion factors from metric units to imperial / US customary units.
| Metric | Imperial / US customary |
|---|---|
| 1 mm | 0.03937 in |
| 1 cm | 0.3937 in |
| 1 m | 39.37 in = 3.28084 ft = 1.09361 yd |
| 1 km | 0.621371 mi = 3,280.84 ft |
Imperial to metric conversion table
| Imperial / US customary | Metric |
|---|---|
| 1 in | 2.54 cm = 25.4 mm (exact) |
| 1 ft | 30.48 cm = 0.3048 m (exact) |
| 1 yd | 0.9144 m (exact) |
| 1 mi | 1.609344 km = 1,609.344 m (exact) |
| 1 nautical mile | 1,852 m (exact) |
Customary Units of Length (Inches, Feet, Yards, Miles)
The US customary and British imperial systems use the same length units:
| Unit | Equals |
|---|---|
| 1 foot | 12 inches |
| 1 yard | 3 feet = 36 inches |
| 1 mile | 1,760 yards = 5,280 feet = 63,360 inches |
So 1 foot to inches = 12 in, and 1 foot to miles = 0.000189 mi (1 ÷ 5,280).
Inches to MM (Including Fractions)
One inch is exactly 25.4 millimeters. Multiply inches by 25.4 to get mm. For tape-measure fractions, divide the fraction first (3/8 = 0.375), then multiply: 0.375 × 25.4 = 9.525 mm.
| Inches | Millimeters | Centimeters |
|---|---|---|
| 1/16 in | 1.5875 mm | 0.1588 cm |
| 1/8 in | 3.175 mm | 0.3175 cm |
| 1/4 in | 6.35 mm | 0.635 cm |
| 3/8 in | 9.525 mm | 0.9525 cm |
| 1/2 in | 12.7 mm | 1.27 cm |
| 5/8 in | 15.875 mm | 1.5875 cm |
| 3/4 in | 19.05 mm | 1.905 cm |
| 7/8 in | 22.225 mm | 2.2225 cm |
| 1 in | 25.4 mm | 2.54 cm |
