All the vehicle based conversion factors on this page are using industry verified values for the unit calculation, and additionally have been referenced from relevant 'conversion of units' sections on Wikipedia.
Conversion tables are often found within the pages of workshop repair manuals for professional and amateur mechanic use. For instance, when using tools for tightening nuts and bolts to a precision, such as a torque wrench, the torque conversion between [ N.m ] and [ lbf.ft] would be a useful converter in this respect. The formula used in the calculations are also shown for each conversion factor unit.
