Tool-Problem Ratio ("TPR") 

Also known as the Aargh Quotient, the Tool-Problem Ratio (“TPR”) is a DIY term expressing the relationship between a physical problem to be fixed and the tool available for the task. A 1:1 ratio reflects that the tool is perfect for the job -- e.g., when a nail clipper is available to trim a toenail, the TPR is 1:1. Ratios of greater than 1:1 indicate that the tool available is excessive relative to the job: a chainsaw generates a ratio of, say, 200:1 for toenail trimming. Ratios of less than 1:1 indicate that the tool at hand is inadequate for the task: a toenail clipper produces a ratio of, say, 1:1000 for cutting down a Christmas tree. Depending on the TPR, responsive behaviors may range from mild (swearing, sighing disgustedly), to driving to the hardware store, to breaking the workpiece or the tool violently.

Faced with a Tool-Problem Ratio ("TPR") of about 1:10 when his flat-blade screwdriver was too big to loosen the Phillips-head screw on his range vent, Bob intoned “Jesus H. Christ” under his breath and motored off to Home Depot.
