What is the Planck length used for?

The Planck length is used as a fundamental scale in quantum gravity and theoretical physics to set characteristic length benchmarks.

Why is the long reed considered an obsolete unit?

The long reed was a traditional unit used in historical land measurement, but its size varied over time and location, making it outdated in modern measurements.

Can this conversion be used for practical measurements?

Due to the extremely small magnitude of the Planck length and variability of the long reed, this conversion is mostly theoretical and not used for practical measurement.
