How to convert:
cm to mm
m to cm
m to mm
m to km
km to m
To convert centimeters (cm) to millimeters (mm):
1 cm = 10 mm
To convert meters (m) to centimeters (cm):
1 m = 100 cm
To convert meters (m) to millimeters (mm):
1 m = 1000 mm
To convert meters (m) to kilometers (km):
1 km = 1000 m
To convert kilometers (km) to meters (m):
1 m = 0.001 km
These conversion rates can be memorized for quick calculations, but if you ever forget, you can always use the following formulas:
1. To convert from a larger unit to a smaller unit, multiply by the appropriate factor.
2. To convert from a smaller unit to a larger unit, divide by the appropriate factor.
For example:
To convert 25 cm to mm:
Since we want to convert from cm to mm, we multiply 25 by 10 (since 1 cm = 10 mm):
25 cm * 10 = 250 mm
To convert 3 m to cm:
Since we want to convert from m to cm, we multiply 3 by 100 (since 1 m = 100 cm):
3 m * 100 = 300 cm
To convert 5 m to mm:
Since we want to convert from m to mm, we multiply 5 by 1000 (since 1 m = 1000 mm):
5 m * 1000 = 5000 mm
To convert 2 m to km:
Since we want to convert from m to km, we divide 2 by 1000 (since 1 km = 1000 m):
2 m / 1000 = 0.002 km
To convert 7 km to m:
Since we want to convert from km to m, we multiply 7 by 1000 (since 1 km = 1000 m):
7 km * 1000 = 7000 m
