Common Length Conversions
Centimeters to Inches
Divide centimeters by 2.54 to get inches. To convert inches to cm, multiply by 2.54.
inches = cm ÷ 2.54
Example: 10 cm ≈ 3.94 inches; 12 inches = 30.48 cm.
Feet to Meters
Multiply feet by 0.3048 to get meters. To convert meters to feet, divide by 0.3048.
meters = feet × 0.3048
Example: 6 feet = 1.8288 meters; 2 meters ≈ 6.56 feet.
Feet to Centimeters
Multiply feet by 30.48 to get centimeters. To convert cm to feet, divide by 30.48.
cm = feet × 30.48
Example: 5 feet = 152.4 cm; 6 feet = 182.88 cm.
Kilometers to Miles
Divide kilometers by 1.609344 to get miles. To convert miles to km, multiply by 1.609344.
miles = km ÷ 1.609344
Example: 5 km ≈ 3.11 miles; 10 miles = 16.09344 km.

| 1 foot | 30.48 cm / 0.3048 m | Exact |
| 1 meter | ≈ 3.280840 feet | Rounded |
| 1 yard | 0.9144 meters | Exact |
| 1 mile | 1.609344 kilometers | Exact |
| 1 kilometer | ≈ 0.621371 miles | Rounded |
| 1 meter | 100 cm / 1,000 mm | Exact |
Height Conversion: Feet and Inches to cm
For a height written in feet and inches, convert the feet to inches first, add the remaining inches, then multiply by 2.54.
height in cm = (feet × 12 + inches) × 2.54
Example: 5 feet 9 inches = 69 inches = 175.26 cm. In the converter above, enter 69 and select Inch to Centimeter. Do not enter 5.9 feet: decimal feet and feet-and-inches notation are different.
| Height | Centimeters |
|---|---|
| 5 feet 0 inches | 152.40 cm |
| 5 feet 5 inches | 165.10 cm |
| 5 feet 7 inches | 170.18 cm |
| 5 feet 9 inches | 175.26 cm |
| 5 feet 11 inches | 180.34 cm |
| 6 feet 0 inches | 182.88 cm |
Millimeters to Inches
To convert mm to inches, divide by 25.4. To convert inches to mm, multiply by 25.4. For example, 10 mm ≈ 0.393701 inches, while 0.5 inches = 12.7 mm.
The examples use the international foot and mile. The symbol ≈ means the result is rounded. In the converter, select more decimal places when you need a more detailed result.
