Free length converter supporting metric and imperial units

Understanding Length Conversions

Length conversion is essential for international communication, travel, construction, and scientific work. Our length converter handles all common units from millimeters to miles, making it easy to convert between metric and imperial systems with precision and confidence.

Supported Units

Metric System:
  • • Millimeters (mm)
  • • Centimeters (cm)
  • • Meters (m)
  • • Kilometers (km)
Imperial System:
  • • Inches (in)
  • • Feet (ft)
  • • Yards (yd)
  • • Miles (mi)

Common Conversion Examples

🏠 Home & Construction

Room dimensions: 12 ft = 3.66 m
Ceiling height: 2.4 m = 7.87 ft
Door width: 36 in = 91.44 cm
Carpet length: 4.5 m = 14.76 ft

✈️ Travel & Geography

Flight distance: 500 mi = 804.67 km
Walking distance: 2 km = 1.24 mi
Building height: 150 m = 492.13 ft
Road width: 3.5 m = 11.48 ft

🛠️ Practical Example: Kitchen Renovation

Scenario: Planning a kitchen renovation with measurements in both metric and imperial.

Original Measurements (Metric):
  • Kitchen length: 4.2 meters
  • Counter depth: 60 centimeters
  • Cabinet height: 72 centimeters
  • Tile size: 30cm × 30cm
Converted (Imperial):
  • Kitchen length: 13.78 feet
  • Counter depth: 23.62 inches
  • Cabinet height: 28.35 inches
  • Tile size: 11.81" × 11.81"

Result: Accurate conversions ensure proper fitting of appliances and materials from different suppliers.

Length Converter FAQ

Which countries use metric vs imperial systems?

Answer: Most countries worldwide use the metric system. Only the United States, Liberia, and Myanmar primarily use imperial/US customary units. The UK uses a mix of both systems. For international business, travel, or scientific work, metric units are standard. Always verify which system is expected when working with international partners.

How accurate are the conversion results?

Answer: Our converter provides results accurate to 6 decimal places, which is more than sufficient for most practical applications. For construction and engineering, this level of precision exceeds typical measurement tolerances. For scientific applications requiring extreme precision, consider the significant figures in your original measurement.

What's the difference between US and UK measurements?

Answer: While both use feet and inches, there are subtle differences in some units. The UK uses imperial gallons (different from US gallons) and stones for weight. For length measurements, feet and inches are essentially identical. Our converter uses standard international definitions that work for both systems.
