History

Meter (m)

The meter, abbreviated as m, serves as the fundamental unit of length in the International System of Units (SI). Initially established during the French Revolution in 1793, it was meant to represent one ten-millionth of the distance from the equator to the North Pole, measured along the Paris meridian. This original measurement relied on geodetic surveys. In 1983, the definition was updated to use the speed of light: a meter is now the length that light travels in a vacuum in 1/299,792,458 of a second. This redefinition provides exceptional accuracy and consistency worldwide, making the meter essential in science, engineering, and daily life. While most countries rely on the meter, some, like the United States, continue to use imperial measurements for certain purposes.

Inch (in)

The inch, abbreviated as in, is a length unit in the imperial and US customary systems. Its history reaches back to ancient civilizations, including the Romans, Egyptians, and Anglo-Saxons. Originally, the inch was determined by the width of a human thumb, but it was eventually set as 1/12 of a foot. Since 1959, the inch has been officially defined as exactly 2.54 centimeters due to an international agreement. Inches are still widely used in the United States, Canada, and the UK, especially for construction, manufacturing, and personal measurements. Even with the global shift to metric units, the inch remains important in certain fields such as technical drawings, screen dimensions, and household tools.
