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) = 0.01 Hectometer (hm).
| Meter (m) | Hectometer (hm) |
|---|---|
| 0.1 | 0.001 |
| 0.5 | 0.005 |
| 1 | 0.01 |
| 2 | 0.02 |
| 5 | 0.05 |
| 10 | 0.1 |
| 25 | 0.25 |
| 50 | 0.5 |
| 100 | 1 |
| 500 | 5 |
| 1000 | 10 |
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 hectometer is a unit of length equal to 100 meters, or one tenth of a kilometer.
1 hm = 100 m = 0.1 km = 10 dam. One square hectometer (hm²) equals one hectare.
To convert hm to meters: multiply by 100. To convert hm to km: divide by 10.
The hectare (1 hm²) is its most common derived application. Occasionally used for short road distances.
A 100-meter Olympic sprint is exactly 1 hectometer. The hectare = 1 hm² is far more famous than the hectometer itself.
Confusing hectometer with hectare — the hectometer is a unit of length, the hectare is a unit of area (1 hectare = 1 hm²).
A football field is roughly 1 hectometer long — use this as a mental benchmark for 100 meters.
