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 & 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.
