Study Notes
Definition
- A meter is a unit of length in the International System of Units (SI)
- It is defined as the distance traveled by light in vacuum in 1/299,792,458 of a second
History
- The meter was originally defined in 1791 as one ten-millionth of the distance from the equator to the North Pole
- In 1889, the International Prototype Meter was established as the standard meter
- In 1960, the meter was redefined in terms of the wavelength of light
- In 1983, the current definition based on the speed of light was adopted
Conversions
- 1 meter = 100 centimeters (cm)
- 1 meter = 1000 millimeters (mm)
- 1 meter = 3.2808 feet (ft)
- 1 meter = 39.370 inches (in)
Uses
- The meter is used as a standard unit of length in many fields, including:
- Science and engineering
- Construction and architecture
- Everyday applications (e.g. measuring rooms, furniture, etc.)
- The meter is also used as a base unit for other units of measurement, such as:
- Kilometer (km) = 1000 meters
- Micrometer (μm) = 0.000001 meters
- Nanometer (nm) = 0.000000001 meters
