Instantly convert between Meters, Feet, Inches, Miles, and more. Essential for engineering, construction, travel, and academic projects.
The world is primarily divided into two systems of measurement for length and distance: the Metric system and the Imperial system.
Used by almost every country in the world (except the USA, Liberia, and Myanmar). It is based on the meter and uses decimals.
Used primarily in the United States and partially in the UK. It is based on historical units like the human foot.
1 Inch = 2.54 Centimeters. This is an exact definition.
1 Mile ≈ 1.609 Kilometers. A 5K run is approximately 3.1 miles.
From Classrooms to Construction Sites.
Whether you are an architecture student converting plans from meters to feet, or a traveler trying to understand speed limits in kilometers vs miles, this tool provides instant clarity.
High precision decimal results.
The symbol for inch is typically a double prime (e.g., 5″) or simply "in". In informal contexts, a double quote mark is often used (e.g., 5").
Our calculator typically outputs results up to 4-6 decimal places for high precision, but trims unnecessary zeros for readability.
