What is the difference between metric and imperial units? ▼
Metric units (meters, centimeters, kilometers) are based on powers of 10, making conversions simple. Imperial units (feet, inches, yards, miles) use different conversion factors. The metric system is used worldwide, while imperial is primarily used in the United States.
How accurate are the conversions? ▼
Our converter uses precise conversion factors and displays results up to 6 decimal places for maximum accuracy. Common conversions like inches to centimeters use exact definitions (1 inch = 2.54 cm exactly).
Can I convert kilometers to miles? ▼
Yes! Select kilometers in the "From" field and miles in the "To" field. 1 kilometer equals approximately 0.621371 miles, or conversely, 1 mile equals approximately 1.60934 kilometers.
What units can I convert? ▼
You can convert between 8 common length units: millimeters (mm), centimeters (cm), meters (m), kilometers (km), inches (in), feet (ft), yards (yd), and miles (mi). All conversions work bidirectionally.
How do I convert feet and inches to centimeters? ▼
Convert each measurement separately, then add the results. For example, 5 feet 8 inches = (5 × 30.48) + (8 × 2.54) = 152.4 + 20.32 = 172.72 cm. Alternatively, convert feet to inches first (5 ft = 60 in), add inches (60 + 8 = 68 in), then convert to cm (68 × 2.54 = 172.72 cm).
