ac — The acre is a unit of area used in the US customary and British imperial systems. It is defined as the area of a rectangle measuring one chain (66 feet) by one furlong (660 feet), which equals exactly 43,560 square feet.
The acre is not part of the International System of Units (SI) but remains widely used in the United States, the United Kingdom, and other countries for measuring land area in real estate, agriculture, and urban planning.
The international acre is based on the international yard (defined as exactly 0.9144 meter), which gives the acre an exact metric equivalent of 4,046.8564224 m².
- Exact factor
- 1 ac = 4,046.8564224 m²
- Examples
-
- 0.17 ac = 687.97 m²
- 0.29 ac = 12,632.4 ft²
- 3.82 ac = 1.5459 ha

cm² — The square centimeter is an SI-derived unit of area equal to exactly 0.0001 m² (one ten-thousandth of a square meter). It represents the area of a square with sides of 1 centimeter.
The square centimeter is widely used in science, engineering, medicine, and manufacturing to express small surface areas such as cross-sections, skin lesions, sensor surfaces, and component footprints.
Because the centimeter is a decimal submultiple of the meter (1 cm = 0.01 m), all conversions between cm² and m² are exact powers of ten, making the square centimeter convenient for precise metric calculations.
- Exact factor
- 1 cm² = 0.0001 m²
- Examples
-
- 1.2 cm² = 0.00012 m²
- 73,000 cm² = 7.3 m²
- 6.8 cm² = 1.054 in²
About the Acre
Facts & Uses
- 1 acre = 43,560 ft² = 4046.8564224 m² exactly = 1/640 of a square mile. The dominant US/UK unit for land area.
- Standard for US and UK real estate (lot sizes, farms, ranches), agriculture (yield per acre), and land titles.
- Used universally in US Public Land Survey System, property tax assessments, and conservation easements.
- Reference scales: 1 acre ≈ a typical US suburban building lot; 10 acres ≈ small farm; 1000 acres ≈ large farm or estate.
Curiosities
- The acre originally meant "the area a yoke of oxen could plow in one day" — about 1 chain (66 ft) wide × 1 furlong (660 ft) long = 43,560 ft².
- A standard American football field (including end zones, 360 × 160 ft) is approximately 1.32 acres.
- The National Mall in Washington, DC is about 309 acres — large enough to host crowds of over 1 million people for inaugurations.
- Approximate equivalents: 1 acre ≈ 0.4047 hectares ≈ 4047 m² ≈ 0.00156 mi².

About the Square Centimeter
Facts & Uses
- 1 cm² = 0.0001 m² exactly. The practical unit for small areas in laboratory work, electronics, and product specifications.
- Standard for cross-sections in physiology (muscle, organ areas), microscopy fields, and printed circuit boards.
- Used in cloth and leather measurements for sample sizes, wound care (dressing sizes), and burn assessment (Body Surface Area in cm²).
- Convenient for density per area calculations: g/cm² for surface density, drops/cm² for paint coverage, lux for illumination intensity.
Curiosities
- A standard postage stamp is approximately 6 cm² (2 × 3 cm); a credit card is about 46 cm² (5.4 × 8.5 cm); an iPhone screen is around 90-110 cm².
- The palm of an adult hand covers approximately 1% of body surface area (~150 cm²) — used in burn triage as the "rule of palm".
- The Burgers vector in materials science and many physics quantities use cm² because it bridges the macroscopic and molecular scales.
- Approximate equivalents: 1 cm² ≈ 0.155 in²; 100 cm² = 1 dm² = 0.01 m².
