Why is the handbreadth not a standard measurement?

Because the handbreadth is based on the width of an adult human hand, its exact size can differ depending on cultural and historical contexts.

What was the Roman actus used for?

The Roman actus was used in ancient times for land measurement, including surveying fields and defining area units such as the actus quadratus.

Can I use this converter for precise modern construction measurements?

No, this converter is intended primarily for historical and academic purposes rather than exact modern measurement tasks.
