Units explained
Square Meter
A square meter is the SI base unit of area, defined as the area of a square with sides of one meter. It is the universal scientific unit for area.
Defined by squaring the meter, which was redefined in 2019 in terms of the speed of light. The meter itself was originally proposed by the French Academy of Sciences in 1791 as 1/10,000,000 of the distance from the equator to the North Pole.
Square meters are the universal SI unit for area, used in real estate (most countries outside the US/UK), construction, physics, engineering, materials science, biology, and nearly all scientific contexts worldwide.
Meter adopted as SI base unit in 1960; current exact definition via speed of light dates to 2019.
Pyeong
A pyeong is a Korean unit of area equal to approximately 3.3058 m² (about 35.58 square feet).
Originated as a traditional East Asian land unit. Korean usage standardizes pyeong at 400/121 m² ≈ 3.3058 m². Defined as the area of a 6-by-6 Korean foot (cheok) square.
Pyeong is the primary unit for residential real estate in South Korea. Although the government tried to phase pyeong out in favor of square meters from 2007, the unit remains in widespread popular use, particularly for apartment sizes.
Traditional East Asian unit; remains in widespread Korean use despite government metric campaigns.

Worked examples
Example 1 — Convert 1 m² to pyeong:
1 × 0.3024986388 = 0.3024986388 pyeong
Example 2 — Convert 100 m² to pyeong:
100 × 0.3024986388 = 30.2498638756 pyeong
Real-world example — Fabric purchase length
Two square meters of fabric equals a value in pyeongs essential for tailors and textile buyers sourcing material from international suppliers that quote in different units.
2 m² × 0.3024986388 = 0.6049972775 pyeong
Real-world example — Maritime depth conversion
A 10-square meter sounding depth converts cleanly into pyeongs. Recreational divers and sailors translate between the two units whenever they read legacy charts against modern depth-sounder displays.
10 m² × 0.3024986388 = 3.0249863876 pyeong
Real-world example — Reference scenario in case of fallback
Conversion between human-scale length units is the everyday workflow of architecture, athletics, and apparel design — three of the most common contexts that span metric and imperial systems.
1 m² × 0.3024986388 = 0.3024986388 pyeong
