Formulas for Converting Length Units
1. Conversion Between Metric Units
- Millimeters → Centimeters: Value in cm = Value in mm ÷ 10
- Centimeters → Millimeters: Value in mm = Value in cm × 10
- Centimeters → Decimeters: Value in dm = Value in cm ÷ 10
- Decimeters → Meters: Value in m = Value in dm ÷ 10
- Meters → Kilometers: Value in km = Value in m ÷ 1000
2. Conversion Between Metric and Imperial Units
- Centimeters → Inches: Value in inches = Value in cm ÷ 2.54
- Inches → Centimeters: Value in cm = Value in inches × 2.54
- Meters → Feet: Value in ft = Value in m ÷ 0.3048
- Feet → Meters: Value in m = Value in ft × 0.3048
- Meters → Yards: Value in yd = Value in m ÷ 0.9144
- Yards → Meters: Value in m = Value in yd × 0.9144
- Kilometers → Miles: Value in miles = Value in km ÷ 1.60934
- Miles → Kilometers: Value in km = Value in miles × 1.60934
