Forum rules
Dear convert-me.com forum visitors,
Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.
All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on convert-me.com FaceBook page
Thank you for being with us and sorry for any inconveniences this could caused.

Joules are a unit of energy, not force. Newtons are unit of force.

bohr or bohr radius (a0)
a unit of distance used in particle physics. 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 10-12 meter. The unit is named for the Danish physicist Niels Bohr (1885-1962), who explained the structure of atoms in a famous paper in 1913.

hartree (Eh)
a unit of energy used in atomic and moleclar physics, equal to about 4.3598 x 10-18 joule or 27.212 electron volts. The unit is named for the British physicist and mathematician Douglas R. Hartree (1897-1958).
So 1 Hartree/Bohr appears to be 4.3598 aJ/52.918 pm = 82.388 nN.
