Metric System

The metric system is a decimal-based system of measurement used worldwide. It's based on units of 10, making conversions straightforward.

  • • 1 kilometer = 1,000 meters
  • • 1 meter = 100 centimeters
  • • 1 centimeter = 10 millimeters
  • • 1 millimeter = 1,000 micrometers

Imperial System

The imperial system is primarily used in the United States and has historical roots in British measurements.

  • • 1 mile = 5,280 feet
  • • 1 yard = 3 feet
  • • 1 foot = 12 inches
  • • 1 inch = 2.54 centimeters

Length Converter – Convert Any Length Measurement Easily

A length converter is a tool that lets you quickly convert between different units of length. This includes metric units like centimeters, meters, and kilometers, as well as imperial units like inches, feet, yards, and miles. Whether you need to convert cm to inches, miles to km, or feet to meters, this guide will explain how to do it with formulas and examples.

Understanding Length Conversion

Length conversion means changing a measurement from one unit of length to another. There are two main systems:

Metric system – uses millimeters (mm), centimeters (cm), meters (m), and kilometers (km).

Imperial/US customary system – uses inches (in), feet (ft), yards (yd), and miles (mi).

A length converter calculator does the math instantly. However, knowing the formulas makes it easy to check your results and understand how the units relate.

Common Length Conversions

CM to Inches

Formula: inches = centimeters ÷ 2.54

Example: 30 cm ÷ 2.54 = 11.81 inches

1 inch equals exactly 2.54 centimeters.

Inch to CM / Inches to CM

Formula: centimeters = inches × 2.54

Example: 10 inches × 2.54 = 25.4 cm

CM to Feet

Formula: feet = centimeters ÷ 30.48

Example: 180 cm ÷ 30.48 = 5.91 feet

Feet to CM / FT to CM

Formula: centimeters = feet × 30.48

Example: 6 feet × 30.48 = 182.88 cm

Meters to Feet / M to FT

Formula: feet = meters × 3.28084

Example: 2 meters × 3.28084 = 6.56168 feet

Feet to Meters / FT to M

Formula: meters = feet ÷ 3.28084

Example: 10 feet ÷ 3.28084 = 3.048 meters

Miles to KM / Miles to Kilometers

Formula: kilometers = miles × 1.60934

Example: 5 miles × 1.60934 = 8.0467 km

KM to Miles / Kilometers to Miles

Formula: miles = kilometers ÷ 1.60934

Example: 10 km ÷ 1.60934 = 6.2137 miles

Meters to Miles

Formula: miles = meters ÷ 1609.34

Example: 5000 meters ÷ 1609.34 = 3.10686 miles

Meters to Inches

Formula: inches = meters × 39.3701

Example: 2 meters × 39.3701 = 78.7402 inches

Yards to Meters / Yards to M

Formula: meters = yards × 0.9144

Example: 50 yards × 0.9144 = 45.72 meters

Meters to Yards / M to Yards

Formula: yards = meters ÷ 0.9144

Example: 20 meters ÷ 0.9144 = 21.872 yards

Feet to Miles / FT to Miles

Formula: miles = feet ÷ 5280

Example: 10,560 feet ÷ 5280 = 2 miles

Centimeters to Inches / CM to IN

Formula: inches = centimeters ÷ 2.54

Example: 50 cm ÷ 2.54 = 19.685 inches

Inches to Centimeters / IN to CM

Formula: centimeters = inches × 2.54

Example: 15 inches × 2.54 = 38.1 cm

How Many Centimeters in an Inch?

1 inch equals 2.54 centimeters exactly.

Metric Conversion for Length

The metric system is based on powers of 10, making it easy to move between units:

1 millimeter = 0.1 centimeter
1 centimeter = 0.01 meter
1 meter = 0.001 kilometer

Example: 2500 meters ÷ 1000 = 2.5 km
