Are all lengths multiples of the Planck length?

Question

If the Planck length is the smallest unit of length that has any physical meaning then is it true to think that all the lengths are multiple of the Planck length?

Answer 1

Yes, all lengths are multiples of the Planck length. All lengths are also multiples of the meter and the mile and the parsec. The Planck length is just another unit length and all lengths may be expressed as some multiple of any unit length.

The Planck scale is expected to be the scale at which quantum gravity is expected to become important. That does not mean that the universe is expected to be formed of Planck length pixels.
