About this tool
Length conversion is one of the most common measurement needs. Whether you're converting your height from feet to meters for international forms, calculating distances for travel, working on construction or DIY projects, or comparing product dimensions, accurate length conversions are essential. The US uses inches, feet, yards, and miles, while most of the world uses the metric system (millimeters, centimeters, meters, kilometers).
Our Length Converter handles all standard units with precision: metric (millimeters, centimeters, meters, kilometers), imperial (inches, feet, yards, miles), and specialized units (nautical miles, fathoms). The calculator uses exact conversion factors, ensuring accuracy for scientific work, engineering projects, and official documentation.
Length conversions appear in countless everyday situations: understanding European height listings (180 cm = ?), converting car specifications from different countries, measuring rooms for furniture, calculating running or cycling distances, understanding TV screen sizes, ordering clothes online from international retailers, and working with construction blueprints. Quick conversions eliminate confusion.
The tool is invaluable for international travelers comparing distances, students learning different measurement systems, construction professionals working with imported materials, athletes tracking workout distances, online shoppers comparing product sizes, and anyone dealing with measurements across different countries. Accurate, instant length conversions make life easier.

FAQs
How many feet are in a meter?
One meter equals approximately 3.281 feet (often rounded to 3.28 ft). To convert meters to feet, multiply by 3.281. To convert feet to meters, divide by 3.281 or multiply by 0.3048. For example, 10 meters = 32.81 feet.
How do I convert inches to centimeters?
One inch equals exactly 2.54 centimeters. To convert inches to cm, multiply by 2.54. To convert cm to inches, divide by 2.54. For example, 10 inches = 25.4 cm, and 100 cm = 39.37 inches. This is one of the most precise conversion factors.
How many kilometers are in a mile?
One mile equals approximately 1.609 kilometers (more precisely, 1.60934 km). To convert miles to km, multiply by 1.609. To convert km to miles, divide by 1.609 or multiply by 0.621. For example, 100 miles = 160.9 km.
What's the easiest way to estimate feet to meters?
A quick rough estimate: divide feet by 3 to get approximate meters (since 1 meter ≈ 3.28 feet). For example, 15 feet ÷ 3 ≈ 5 meters (actual: 4.57 m). For precise measurements, use the exact conversion factor of 0.3048.
How do I convert my height from feet and inches to centimeters?
First convert to total inches: multiply feet by 12 and add remaining inches. Then multiply by 2.54 to get centimeters. Example: 5'10" = (5 × 12 + 10) = 70 inches × 2.54 = 177.8 cm. Or convert feet to cm (×30.48) and inches to cm (×2.54) separately, then add.
What's the difference between yards and meters?
They're close but not identical. One yard equals 0.9144 meters (about 91.44 cm). One meter equals 1.094 yards (about 39.37 inches). A meter is slightly longer—by about 3.4 inches. In sports, a 100-yard football field is 91.44 meters, shorter than a 100-meter track.
Why do some countries use different measurement systems?
Most countries adopted the metric system (meters, kilometers) for its decimal simplicity. The US primarily uses imperial units (feet, miles) for historical reasons, though science and medicine use metric. UK uses a mix. Understanding both systems is valuable for international communication.
How precise should length conversions be?
It depends on context. Casual use (height, travel) can round to 2 decimals. Construction might need 3-4 decimals. Scientific or engineering work requires maximum precision. Our converter provides precise values so you can round as needed for your specific application.
What is the difference between metric and imperial systems?
The metric system (meters, kilometers) uses base-10 and is used worldwide. The imperial system (feet, inches, miles) is primarily used in the US, UK, and a few other countries. Metric is easier for calculations (100 cm = 1 m, 1000 m = 1 km), while imperial has more varied conversions (12 inches = 1 foot, 3 feet = 1 yard, 5280 feet = 1 mile).
What is a nautical mile and when is it used?
A nautical mile (1,852 meters or 1.15 statute miles) is used in marine and aviation navigation. It's based on Earth's circumference - one nautical mile equals one minute of latitude. Ships and aircraft use knots (nautical miles per hour) for speed. It's longer than a regular mile and essential for navigation charts.
