Summary
About these automotive Conversion Tools
Conversion tables for vehicles 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 calculation are also shown for each conversion factor unit.
Verification
These vehicle-focused conversion tools are using NIST Industry Verified Values for unit calculations, and additionally have been referenced from relevant conversion of units sections from Wikipedia.
