## Torque Wrench Extension Calc. Reviews in United States

### ****- "Spare, but works"
Note to users:  the units are irrelevant so long as you’re consistent. 

The units don’t have to be all metric or all English.

e.g. : if you use furlongs for both lengths and kg-inches for both torques, you get the right answer.   

It’s also important to know how to use a torque wrench with an extender:  
- Always keep the wrench and extension in line. (Not at an angle)
- Always push from the center of the torque wrench’s handle (or wherever you measured L1 & L2 from)

If you do those, it works great!

### ***-- "Meh"
I have no idea what units this program is asking for or giving me
-- FoxyJosh, 2014-12-08

### ****- "Works as advertised"
Formula is the same as what is in  Sikorsky's standard practices chapter. App gave the same answer as my calculator when given the same numbers.
