Conversion

Torque can be expressed in several types of units when expressing a wrench's capacity.

The same units are used to specify a limit set or audit target for a fastener.

Converting from one unit of measurement to another is done by applying a conversion factor.

Conversion Factors:

• One ft. lb. = 1.35582 Newton Meters
• One Newton Meter = One Newton Meter
• One ft. lb = .138255 kilogram meters
• One kilogram meter = 7.23301 ft. lb.

For example:

• If one ft. lb = 1.35582 Newton Meters
• and you have a torque wrench measuring 458 ft. lbs
• and you want to determine the torque in Newton Meters
• next convert from ft. lb. to Nm by multiplying 458 x 1.35582 = 620.97 Nm
• so a 458 ft. lb. of torque is also 620.97 Nm.
