To convert meters to feet: multiply by 3.28084. To convert meters to inches: multiply by 39.3701.
1 m = 100 cm = 1,000 mm = 0.001 km. It is the base unit, so all other metric length units are derived by powers of 10.
For example, 1 Meter (m) = 100 Centimeter (cm).
| Meter (m) | Centimeter (cm) |

| 0.1 | 10 |
| 0.5 | 50 |
| 1 | 100 |
| 2 | 200 |
| 5 | 500 |
| 10 | 1000 |
| 25 | 2500 |
| 50 | 5000 |
| 100 | 10000 |
| 500 | 50000 |

The meter is the base unit of length in the International System of Units (SI), defined as the distance light travels in a vacuum in 1/299,792,458 of a second.
1 m = 100 cm = 1,000 mm = 0.001 km. It is the base unit, so all other metric length units are derived by powers of 10.
To convert meters to feet: multiply by 3.28084. To convert meters to inches: multiply by 39.3701.
Used for measuring room dimensions, building heights, athletic track distances, fabric lengths, and everyday object sizes.
The speed of light is exactly 299,792,458 m/s by definition — the meter is actually defined from this constant, not the other way around.
Confusing meters with yards — a meter is about 10% longer than a yard. Also, mixing up 'm' (meter) with 'mi' (mile).
Remember: a doorway is roughly 2 meters tall, and an adult's stride is about 0.7–0.8 meters. Use these as mental benchmarks.
The centimeter is a unit of length equal to one hundredth of a meter (10⁻² m), or 10 millimeters.
1 cm = 0.01 m = 10 mm = 0.3937 inches. There are 2.54 cm in one inch.
To convert cm to inches: divide by 2.54. To convert inches to cm: multiply by 2.54.
Measuring height, waist circumference, screen sizes, furniture dimensions, and map scales.
The CGS system was the primary scientific system for over a century. 1 cm is roughly the width of an adult fingernail.
Confusing cm and inches — a common error in international contexts. Always verify which system a measurement uses.
Your fingernail width is roughly 1 cm — a handy mental reference that's always available.
