Convert m to cm

仪表

定义
A meter (symbol: m) is the SI’s fundamental unit of length, defined as the distance light travels in a vacuum in 1⁄299 792 458 of a second. This light-based standard was adopted in 1983 and slightly refined in 2019 to align with updates to the definition of the second.

起源

• 1793: One ten-millionth of the meridian from the Equator to the North Pole.

• 1889: Length of a platinum-iridium prototype bar at 0 °C.

• 1960: Specified by a fixed number of wavelengths of krypton-86 radiation.

• 1983-2019: Anchored to the constant speed of light.

今天的使用情况
Meters are everywhere—from scientific experiments and engineering blueprints to the height markings on walls and the distance markers on roads (outside the U.S.). In international trade and global standards, the meter reigns as the universal length unit.

厘米

定义
A centimeter (symbol: cm) equals one-hundredth of a meter (0.01 m). It’s a convenient subdivision of the meter for measuring smaller spans.

起源
由前缀 厘 （拉丁语 分, “hundred”) and “meter,” the centimeter embodies the metric system’s base-10 design, making unit scaling as simple as moving a decimal point.

今天的使用情况
Centimeters are used worldwide for tasks requiring more precision than meters provide: measuring heights in medical charts, detailing product dimensions, or laying out classroom rulers—especially in countries that have fully metrified.
