Length Converter

The Length Converter calculates exact, real-time domain outputs in active voice. The Length Converter transforms any distance measurement across all 9 metric and imperial length units simultaneously, including human height conversions between centimeters (cm) and Feet + Inches (ft' in").

Length Converter Input Parameters & Defaults

Length in Meters (m) [e.g. 1.75m = 175cm]1.75Length in meters (enter cm / 100 for height).

Length Converter Mathematical Formula

1\text{ in} = 2.54\text{ cm}, \quad 1\text{ ft} = 30.48\text{ cm}, \quad 1\text{ m} = 3.2808399\text{ ft}, \quad 1\text{ mi} = 1.609344\text{ km}

Length Converter Worked Example

Converting 1.75 meters into centimeters, feet, inches, and feet-and-inches.

  1. Centimeters = 1.75 × 100 = 175.0 cm; Millimeters = 1,750 mm.
  2. Total Inches = 175 / 2.54 = 68.8976 inches.
  3. Total Decimal Feet = 68.8976 / 12 = 5.7415 ft -> 5 feet, 8.90 inches.

Note that 5.74 feet does NOT mean 5 feet 7.4 inches—because there are 12 inches in a foot, 0.7415 × 12 = 8.90 inches (5' 8.9").

Length Converter Frequently Asked Questions

Q: How do I convert cm to feet and inches accurately?

Divide centimeters by 2.54 to get total inches. The integer quotient when dividing total inches by 12 is your feet, and the remainder is your inches (not the decimal part of feet × 10!).
