Also found this:
"ft-lb" and "lb-ft" are not interchangeable.While "ft-lb" is the correct term for torque in English units, "lb-ft" is a measure of something else altogether. Despite this, in practice, torque units are commonly called the foot-pound (denoted as either lb-ft or ft-lb) or the inch-pound (denoted as in-lb). Practitioners depend on context and the hyphenated abbreviations to know that these refer to neither energy nor moment of mass.
BTW, when you publish in our Society Journal you will use Nm and can follow with (what used to be called US Customary.)

While you are technically correct (ft-lb is a measurement of work) most torque wrenches have markings that are in ft-lb so it gets confusing calling out torque on a torque wrench as lb ft.
