megameter to hectometer
Convert megameter (Mm) to hectometer (hm). Use an editable length converter, conversion formula, and reference table.
1 Mm = 10,000 hm
Conversion formula
One megameter equals 10,000 hectometer. Multiply your value in megameter by this factor to get hectometer. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 megameter:5 × 10,000 = 50,000 hm

About these measurements
Length measures the distance between two points.
The base reference used here is the meter. One megameter is 1,000,000 base units; one hectometer is 100 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 Mm to hm?
Multiply the quantity in Mm by 10,000. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the hectometer to megameter converter.
