Complete Length Conversion Guide
This guide explains every major length conversion including kilometre, metre, centimetre, millimetre, inch, foot, yard and mile. You’ll find formulas, examples, quick tables and everyday uses — perfect for students, travelers, engineers, architects and anyone who measures distances.
Kilometre to Metre (KM → M)
1 kilometre equals 1000 metres. This is commonly used in maps, running distances and road measurements.
Formula
Metres = Kilometres × 1000
Example
2.5 km × 1000 = 2500 m
| KM | M |
|---|---|
| 1 | 1000 |
| 5 | 5000 |
| 10 | 10000 |
Metre to Kilometre (M → KM)
Use this when converting shorter distances into long-distance measurement.
Formula
Kilometres = Metres ÷ 1000
Example
1500 m ÷ 1000 = 1.5 km
Centimetre to Metre (CM → M)
Centimetres are used for measuring small objects, heights and home decor.
Formula
Metres = Centimetres ÷ 100
Example
250 cm ÷ 100 = 2.5 m
Metre to Centimetre (M → CM)
Formula
Centimetres = Metres × 100
Example
1.7 m × 100 = 170 cm
Metre to Feet (M → FT)
Feet are commonly used in the United States for height, building plans and sports measurements.
Formula
Feet = Metres × 3.28084
Example
1.8 m × 3.28084 = 5.90 ft
Feet to Metre (FT → M)
Formula
Metres = Feet ÷ 3.28084
Example
6 ft ÷ 3.28084 = 1.828 m
Inch to Centimetre (IN → CM)
Formula
Centimetres = Inches × 2.54
Example
10 in × 2.54 = 25.4 cm
| Inches | Centimetres |
|---|---|
| 1 | 2.54 |
| 5 | 12.7 |
| 12 | 30.48 |
Centimetre to Inch (CM → IN)
Formula
Inches = Centimetres ÷ 2.54
Example
30 cm ÷ 2.54 ≈ 11.81 in
Mile to Kilometre (MI → KM)
Formula
Kilometres = Miles × 1.60934
Example
3 mi × 1.60934 = 4.828 km
Kilometre to Mile (KM → MI)
Formula
Miles = Kilometres × 0.621371
Example
10 km × 0.621371 = 6.2137 mi
Yard to Metre (Yard → M)
Formula
Metres = Yards ÷ 1.09361
Example
5 yards ÷ 1.09361 = 4.572 m
Metre to Yard (M → Yard)
Formula
Yards = Metres × 1.09361
Example
10 m × 1.09361 = 10.936 yards
Millimetre (MM) Conversions
MM → CM
Centimetres = Millimetres ÷ 10
MM → M
Metres = Millimetres ÷ 1000
MM → Inch
Inches = Millimetres ÷ 25.4
