Why is the US survey mile different from the international mile?

The US survey mile is based on historically defined survey feet that differ slightly from international feet, maintaining consistency with legacy cadastral data in the United States.

What is a dekameter used for?

A dekameter, equal to 10 meters, is used to express distances on a scale of tens of meters, common in topographic mapping, meteorology, and infrastructure measurements.

Can I use this converter for everyday measurements?

While possible, dekameters are less common in daily use, so ensure that the output unit aligns with your intended measurement context.
