The formulas for conversion are represented below:
dm = km x 10000
Example: 30 kilometers in decimeters:
dm = km x 10000
dm = 30 x 10000
dm = 300000
km = dm / 10000
Example: 1500 decimeters in kilometers:
km = dm / 10000
km = 1500 / 10000
km = 0,15
Considering that 1 kilometer is equivalent to 10000 decimeters, you can use a rule of three to get that 1.5 km equals 15000 decimeters.
1 km - 10000 dm
1,5 km - x
Apply the rule of three and get:
x km = 1500 dkm2
x = 15000 dm
If every 10000 decimeters we have 1 kilometer, just divide the number of meters (100000) by 10000, so you will get that 10000 dm equals 10 km. Observe the calculation below:
km = dm / 10000
Km = 100000 / 10000
km = 10
