hectometer to decimeter
Convert hectometer (hm) to decimeter (dm). Use an editable length converter, conversion formula, and reference table.
1 hm = 1,000 dm
Conversion formula
One hectometer equals 1,000 decimeter. Multiply your value in hectometer by this factor to get decimeter. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 hectometer:5 × 1,000 = 5,000 dm

About these measurements
Length measures the distance between two points.
The base reference used here is the meter. One hectometer is 100 base units; one decimeter is 0.1 base units.
Important distinctions
International feet and inches are used. Survey feet are not included.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
How do I convert hm to dm?
Multiply the quantity in hm by 1,000. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the decimeter to hectometer converter.
