Q:What is the exact conversion formula between Centimeters and Feet & Inches?
By international treaty, 1 inch equals exactly 2.54 cm, and 1 foot equals 12 inches (30.48 cm). To convert cm to feet and inches: total inches = cm / 2.54; feet = floor(total inches / 12); inches = total inches mod 12. To convert feet and inches to cm: cm = (feet × 30.48) + (inches × 2.54).
Q:Why does 1 foot equal exactly 30.48 centimeters?
In 1959, the International Yard and Pound Agreement standardized 1 yard as exactly 0.9144 meters. Because 1 yard contains 3 feet, 1 foot became exactly 0.9144 / 3 = 0.3048 meters, which is 30.48 centimeters exactly.
Q:How do I convert decimal feet (e.g., 5.83 ft) into feet and inches?
Take the whole number as feet (5 ft). Multiply the decimal fraction by 12 to obtain inches: 0.83 × 12 = 9.96 inches (approx. 5 ft 10 in or 177.7 cm). Never confuse decimal feet with feet and inches.
Q:How are builder fractional inches (1/16ths) calculated?
Carpenters' tape measures in the US and UK divide each inch into sixteenths. We take the decimal remainder of an inch, multiply by 16, round to the nearest whole number, and reduce the fraction via the greatest common divisor (e.g., 14/16 reduces to 7/8 in).
Q:What are common benchmark height conversions between cm and feet/inches?
Common benchmarks include: 152.4 cm = 5'0"; 160 cm ≈ 5'3"; 170 cm ≈ 5'7"; 175 cm ≈ 5'9" (global male average); 180 cm ≈ 5'11"; 182.88 cm = 6'0"; 190 cm ≈ 6'3"; 200 cm ≈ 6'6 3/4".
Q:Is this conversion exact for passports, medical records, and sports combines?
Yes. Official border control, civil aviation authorities, and athletic draft combines (such as the NBA, NFL, and FIFA) strictly use the legal 2.54 cm per inch ratio.
Q:What is the difference between the International Foot and the historical US Survey Foot?
The International Foot is exactly 0.3048 m. The historical US Survey Foot was defined in 1893 as 1200/3937 m (approx. 0.30480061 m). On January 1, 2023, the National Institute of Standards and Technology (NIST) officially retired the US Survey Foot in favor of the international foot for all surveying.
To convert centimeters (cm) to feet (ft), divide the length by 30.48. Alternatively, multiply by approximately 0.0328084.
