Step 1: Recall the official definition of the meter from the International System of Units (SI). The meter (symbol: m) is the base unit of length. 1~m = distance traveled by light in vacuum in (1)/(299792458)~s where c = 299792458~m/s (exact, speed of light in vacuum) and 1~s is defined by cesium-133 hyperfine transition frequency _Cs = 9192631770~Hz (exact). Step 2: Historical context (for understanding). Originally (1791): 1~m ≈ 1/10000000 of Earth meridian quadrant (Paris to equator). Updated 1889: distance between platinum-iridium bars. Refined 1960: 1650763.73 wavelengths of krypton-86 orange-red line. Current (1983, reaffirmed 2019): light-based for invariance. Step 3: Practical equivalents (with units). 1~m ≈ 39.3701~in ≈ 3.28084~ft ≈ 100~cm = 1000~mm The meter is the SI unit of length, exactly defined as the distance light travels in vacuum in (1)/(299792458) seconds. 1 m = distance light travels in vacuum in (1)/(299792458) s
