Multiply the original measurement by "unit fractions" which change the units without changing the measurement.
5280 feet 1 meter 1 decameter
25.3 miles * ----------- * ----------- * -------------
1 mile 3.28 feet 10 meters
With that multiplication, the units cancel, leaving the measurement in decameters. Since in each fraction the numerator and denominator are equivalent measurements, each fraction has the value 1; so the multiplications do not change the actual measurement.
Use a calculator....

The statement "10 decameters is 1 meter" in the post by @josgarithmetic is ABSOLUTELY and TOTALLY W R O N G.
So, ignore his post, if you don't want to make a HUGE MISTAKE.
1 decameter is 10 meters, in opposite.
I also can add that this unit of measurement "1 decameter" is NEVER USED in practice.
I worked about 40 years in Civil Engineering for various industries, so I know this subject.
