What Is This Tool?
This online converter allows users to transform length measurements expressed in atomic units (a.u., b), based on the Bohr radius, into dekameters (dam), an SI-derived unit equal to ten meters. It helps relate quantum-scale distances to practical macroscopic units.
How to Use This Tool?

Conversions produce very small numbers, which may not be practical for everyday distances.
-
Rounding and precision considerations are important when linking quantum and macroscopic units.
-
The atomic unit of length applies only to extremely small scales typical in atomic physics.
Frequently Asked Questions
-
What exactly is an atomic unit of length?
-
It is the Bohr radius, a fundamental scale in atomic physics representing the mean electron–proton separation in the ground state of hydrogen.
-
How many meters equal one dekameter?
-
One dekameter equals 10 meters and is used to express lengths on the scale of tens of meters.
-
Why convert atomic units of length to dekameters?
-
This helps connect atomic scale distances with larger, practical units useful in fields like geospatial analysis and quantum chemistry.
