You acknowledge what they really mean is ft lbf right? Usually pronounced foot pounds. It's a common unit of torque in the imperial system. I feel like people are just jumping on the bandwagon. This is coming from a diehard Nm preferrer, we need to choose our battles. How bout we die on the hill of bite force being measured with units of pressure? Like really? Fucking pressure? Utterly meaningless as a unit of comparison between bite strength of animals, since all you need to get a bigger number is SHARPER FUCKING TEETH.
