Acre (ac) - Imperial/US land area
Acre is a traditional unit of area used for land measurement in the UK, US, and other countries. Used in real estate, agriculture, and land records; metrically it converts exactly because the foot is defined in meters.
- Symbol: ac
- System: Imperial/US customary (non-SI, accepted for use with SI
- Exact relations: 1 acre = 43,560 ft² = 4,840 yd² = 160 square rods (perches/poles) = 10 square chains
- Metric equivalents (exact): 1 acre = 4046.8564224 m² ≈ 0.40468564224 ha
- Typical examples: suburban lots (fractions of an acre); farm fields of tens to hundreds of acres; sports complexes measured in multiple acres
Square centimeter (cm²) - small metric area
Square centimeter is a metric unit of area equal to the area of a square with sides of 1 centimeter. Used for labeling, small component footprints, and cross-sections in science and engineering.
- Symbol: cm²
- System: SI derived unit
- Exact relations: 1 cm² = (0.01 m)² = 0.0001 m² = 100 mm²; 1 m² = 10,000 cm²
- Imperial/US equivalents: 1 cm² ≈ 0.15500031 in² ≈ 0.001076391 ft²
- Typical examples: postage stamp area (~4–6 cm²); PCB pad areas; small sensor cross-sections
