Unit definitions
What is a meter (m)?
- Description: The meter is the base unit of length in the International System of Units (SI).
- Symbol: m
- Common uses: Used globally for scientific, engineering, and everyday measurements.
- Definition: Since 1983, a meter has been defined as the distance light travels in a vacuum in 1/299,792,458 seconds.
What is a fathom (ftm)?
- Description: A fathom is a nautical unit primarily measuring water depth.
