Hectometers per second to decimeters per second converter
Convert hectometers per second (hm/s) to decimeters per second (dm/s). Calculate any value, follow the unit-factor steps and check a conversion table.
Updated · How we checkUse a decimal point, such as 2.5. Enter a value in hm/s; the result is in dm/s.
Formula
Worked example
Convert 1 hm/s to dm/s:
1 hm/s ≈ 1,000 dm/s
Multiply your hm/s value by the factor above. The calculator uses the full conversion factor before rounding the displayed answer.

What hectometers per second measure
Hectometers per second (hm/s) represent speed. One unit equals 10^2 m/s. Speed is distance per elapsed time. These units prefix the meter while keeping one second fixed.
Reading the result in decimeters per second
Decimeters per second (dm/s) represent speed. One unit equals 10^-1 m/s. Speed is distance per elapsed time. These units prefix the meter while keeping one second fixed.
Where this conversion helps
Convert a speed value used in motion, flow or timing calculations. Speed is not acceleration. Converting speed does not estimate how fast the object changes velocity.
How the scale changes
The input unit has a factor of 1e2 m/s; the output unit has a factor of 1e-1 m/s. Multiply the entered number by the input factor, then divide by the output factor. The physical quantity stays the same while its numerical representation changes.
Reading very small or large results
Scientific notation keeps very small and large values readable: 2.5e-6 means 0.0000025. The converter calculates with 50 significant digits internally and displays up to 10. Exact unit definitions do not remove uncertainty from the original measurement.
