Quick Reference

1 Bohr = 2.117e-7 Q

1 Q = 4724290.41 Bohr

Bohr to Q Conversion Formula

To convert Bohr to Q, multiply by 2.117e-7.

Q = Bohr × 2.117e-7

Bohr = Q × 4724290.41

To convert Q back to Bohr, divide by 2.117e-7 (or multiply by 4724290.41).

About These Units

About Bohr

The Bohr is a unit of distance commonly used in particle physics. It was named after the Danish physicist Niels Bohr (1885-1962), who explained the structure of atoms in a famous paper in 1913. The Bohr radius represents the mean distance between the proton and the electron in an unexcited hydrogen atom. It equals about 52.918 picometers (pm), or 52.918 x 10e-12 meter.

About Q

The Q is a metric unit of distance equal to exactly 0.25 millimeter (9.8425 mils) used by typographers and page designers in Japan, in Germany, and in other countries in preference to the traditional point. One Q is equal to about 0.71 point, a little more or less depending on the exact definition of the point. This unit is also spelled kyu.
