Meter (m) – The Fundamental Unit of Length
Themeteris the base unit of length in the International System of Units (SI). It is defined by the distance light travels in vacuum in 1/299,792,458 of a second. This precise definition makes the meter a universal standard in science, engineering, and everyday measurements.
History & Background
The meter was originally conceived during the French Revolution as a means to standardize measurements based on natural phenomena. It has since evolved into a highly precise measurement system used around the world.
Conversion Factors
- 1 m = 100 cm
- 1 m = 1000 mm
- 1 m = 0.001 km
- 1 m ≈ 3.28084 ft
