Convert Pound-force to Tonne-force

Pound-force → Tonne-force
lbf × 0.0004535924 = tf tf × 2204.623 = lbf

To convert pound-force (lbf) to tonne-force (tf), multiply the pound-force value by 0.0004535924. 1 lbf = 0.0004535924 tf, and 1 tf = 2204.623 lbf. The conversion is a linear scaling with no offset, so the same factor applies to any value.

Going the other way? Convert tf to lbf.
