Length converter

gigameter to decameter

Convert gigameter (Gm) to decameter (dam). Use an editable length converter, conversion formula, and reference table.

100,000,000

1 Gm = 100,000,000 dam

Calculated in your browser

Conversion formula

dam = Gm × 100,000,000

One gigameter equals 100,000,000 decameter. Multiply your value in gigameter by this factor to get decameter. For the reverse conversion, divide by the same factor.

Worked example

To convert 5 gigameter:
5 × 100,000,000 = 500,000,000 dam

About these measurements

Length measures the distance between two points.

The base reference used here is the meter. One gigameter is 1,000,000,000 base units; one decameter is 10 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.
