decimeter = dm centimeter = cm meter = m kilometer = km
You can't convert that.
With 10 decimeters to a meter, 600 decimeter is a lot more than 6 m.
There are 10 cm in a dm and so a decimeter is 1/10 of a meter
1 metre = 1000 millimetres4 metres = 4000 millimetres
1 m = 10 decimeter
Divide by ten.
10
decimeter
decimeter = dm centimeter = cm meter = m kilometer = km
Multiply by 1000: 4000 mm = 4 m
The prefix milli- means "one thousandth" so to convert 4 m to millimeters you would multiply by 1000. 4 m = 4000 millimeters.
To convert from decimeters to meters, you divide by 10. So, 70.25 dm is equal to 7.025 meters.
You can't convert that.
Divide by 1000.
To convert decimeters to millimeters, you multiply the number of decimeters by 100. This is because there are 10 millimeters in one centimeter, and 10 centimeters in one decimeter. So, 1 decimeter is equal to 100 millimeters.
3.9 inches per decimeter, or approximately 4 inches per decimeter.
