ISO 80000 & International Stature Metrology

Under international treaty (1959 International Yard and Pound Agreement), 1 inch is defined as exactly 2.54 centimeters:

• Feet and Inches to Centimeters: cm = [(Feet × 12) + Inches] × 2.54

• Centimeters to Feet and Inches: Total Inches = cm2.54, then Feet = Inches12 , Remaining Inches = Total Inches ±od12

• Meters: Meters = cm100

Common Height Conversion Reference Table

• 5 ft 0 in: = 60.0 in = 152.4 cm = 1.524 m

• 5 ft 4 in (US Avg Female): = 64.0 in = 162.6 cm = 1.626 m

• 5 ft 7 in: = 67.0 in = 170.2 cm = 1.702 m

• 5 ft 9 in (US Avg Male): = 69.0 in = 175.3 cm = 1.753 m

• 5 ft 10 in: = 70.0 in = 177.8 cm = 1.778 m

• 6 ft 0 in: = 72.0 in = 182.9 cm = 1.829 m

• 6 ft 2 in: = 74.0 in = 188.0 cm = 1.880 m

• 6 ft 4 in: = 76.0 in = 193.0 cm = 1.930 m

How to Use This Calculator

The Formula

Conversion factors (to SI base unit or reference unit):

ft: 5.0

inch: 9.0

cm: 175.26

Worked Example

A traveler measuring 6 ft 0 in converts their height to 182.88 cm (1.829 m) for a European medical questionnaire.

Understanding Your Result

Unit conversion precision: round to the same number of significant figures as your original measurement. Converting 6 feet to meters gives 1.8288 m — but if your measurement was approximate (±1 inch), expressing more than 2 decimal places is false precision. For international trade and technical specifications, SI units (meters, kilograms, liters) are the standard. US customary units (feet, pounds, gallons) differ from Imperial UK units: 1 US gallon = 3.785 L vs. 1 UK gallon = 4.546 L.
