Convert cm to m
Centimeter
التعريف
A centimeter (cm) is an SI unit of length equal to one-hundredth of a meter (0.01 m). It provides a handy subdivision of the meter for measurements too small to use full meters.
History & Origin
Built from the Latin prefix centi- (“hundred”) plus “meter,” the centimeter became part of the metric system’s decimal structure in the late 18th century. While the meter itself has evolved—from Earth-based definitions to a light-speed constant—one centimeter has always remained 1⁄100 of that unit.
الاستخدام الحديث
Centimeters are used worldwide for everyday tasks and scientific work: measuring height charts, classroom rulers, product dimensions, and small distances wherever the metric system is adopted.
Meter
التعريف
A meter (m) is the SI’s base unit of length, defined as the distance light travels in 1⁄299 792 458 of a second. This constant-based definition, established in 1983 and refined in 2019, ensures unchanging precision.
History & Origin
1793: Conceptualized as one ten-millionth of the Earth’s quadrant from Equator to North Pole
1889: Realized by an international platinum-iridium prototype bar
1960: Recast in terms of krypton-86 emission wavelengths
1983–2019: Tied directly to the speed of light
الاستخدام الحديث
Meters dominate global measurements—in science, engineering, construction, and everyday distances. Though the U.S. often uses feet and miles in daily life, meters underpin its scientific and trade standards.
