Length & Distance Converter — Free & Instant

What this converter does

Centimeters, inches, feet, yards, meters and miles converted both ways. Type a value into the converter above and every other unit updates at the same time, so you never have to run the same conversion twice.

How to use the tool above

1. Pick the unit you are starting from and type your value.
2. Read the matching value in the unit you need — all supported units are shown together.
3. Copy the figure you need. For documents and specifications, keep the same number of decimal places throughout.

The conversion, in plain words

Each unit is stored as a factor against a single base unit, so a conversion is one multiplication and one division:

• value in Centimeters (cm) = value in Meters (m) × 100.0000

That is why the results are exact rather than table lookups, and why unusual values convert as cleanly as round ones.

Worked examples

• 1 Meters (m) = 100.0000 Centimeters (cm)
• 10 Meters (m) = 1,000.0000 Centimeters (cm)

Units supported

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

Common mistakes to avoid

• Confusing similar unit names. US and imperial units share names but not always sizes — check which system a document expects.
• Rounding mid-chain. Convert once, straight to the unit you need, instead of hopping through an intermediate unit.
• Dropping precision on small values. Keep more decimal places when the value is close to zero.
