Length Converter: How to Convert Between Meters, Feet, Inches, and Miles for Any Project

Converting between meters, feet, inches, and miles is something nearly everyone needs to do at some point — whether you are measuring a room for new furniture, following a woodworking plan from a different country, calculating running distance, or comparing property sizes. Instead of fumbling with formulas, use our Length Converter for instant, accurate conversions across dozens of unit pairs.

Common Length Conversions at a Glance

From	To	Formula	Example
Inches	Centimeters	in x 2.54	12 in = 30.48 cm
Feet	Meters	ft x 0.3048	10 ft = 3.048 m
Yards	Meters	yd x 0.9144	100 yd = 91.44 m
Miles	Kilometers	mi x 1.609	5 mi = 8.045 km
Meters	Feet	m x 3.281	100 m = 328.1 ft
Kilometers	Miles	km x 0.621	10 km = 6.21 mi

When You Will Need Length Conversions

Length conversions come up in more daily situations than you might expect:

• Home improvement: A European furniture manual lists dimensions in centimeters, but your tape measure reads in inches. Convert 80 cm to 31.5 inches to be sure that desk fits.
• Travel: Hiking trails in the US are measured in miles; in Europe, they use kilometers. Knowing 5 miles is about 8 km helps plan your day.
• Fitness: Treadmill distances, running tracks (400 m = 0.25 mi), and swimming pool lengths vary by country.
• Shipping: Parcel dimensions may need conversion between metric and imperial depending on the carrier and destination.
• Crafting and sewing: Patterns from international designers often use different units than your ruler.

For any of these situations, our Length Converter handles the math instantly — just enter the number and select your units.

Quick Mental Math Shortcuts

When you do not have a calculator handy, these approximations are close enough for most daily use:

• 1 inch is roughly the width of your thumb — about 2.5 cm
• 1 foot is about the length of an adult forearm — roughly 30 cm
• 1 meter is a little longer than a yard — about 3.3 feet
• 1 kilometer is about 0.6 miles — a 5K run is roughly 3.1 miles
• 1 mile is about 1.6 km — so 60 mph is roughly 96 km/h

For precise work — construction, engineering, or baking recipes converted from European cookbooks — always use the Length Converter to avoid costly measurement errors.

Length Conversion Cheat Sheet

Keep these common equivalences handy:

• 1 inch = 2.54 cm (exact)
• 1 foot = 12 inches = 30.48 cm
• 1 yard = 3 feet = 0.914 m
• 1 mile = 1,760 yards = 1.609 km
• 1 meter = 100 cm = 39.37 inches
• 1 kilometer = 1,000 m = 0.621 miles
