Thimble: use the lower (N·m) number.
N·m calculator
Main-scale reading + thimble contribution = total torque
N·m
N·m
The lower-row thimble numbers are already in N·m, so the multiplier is ×1: a marking of 4.07 adds 4.07 N·m.

It only adds what you type. It never reads the wrench for you.

Wrench Practice · Newton-meters
Same wrench, other side
This target is in N·m, and the targets now alternate between ft-lb and N·m. The N·m main scale is printed on the back of the barrel. On the thimble, the upper row of numbers is ft-lb and the lower row is N·m. Use the lower row.
The setting does not change when the wrench turns over. Only the scale you read changes.

What do you want to practise?
Practice shows extra guidance and is never saved to the leaderboard.
LEVEL 2
Torque the Wheel
Three rounds, each harder than the last. In every round, set the wrench to a new target, then tighten each lug nut once in the right order.
1 · Five lugs2 · Six lugs3 · Eight lugs
Five lugs use a star pattern. Six and eight lugs use opposite pairs in a crisscross order. Each new pattern is demonstrated first. The timer is paused during demos.
Real vehicle torque specs and tightening procedures must follow the manufacturer's instructions.
