Metric Conversion

I Love this app!!! I noticed a problem however in the metric conversion. If you put 1.0 in the inch to mm conversion, one would expect to see an answer of 25.4 mm. This app gives an answer of .0394, which is the correct number for 1.0 mm.

Conversely, if you enter a number in the mm window, it will give you the same answer as if you put the same number in the inch window.

I thought this was a glitch maybe in my iPhone, but soon found it was the same on my iPad.

Even so, I use this app in my shop a lot and I love the time it saves me, especially in angle calculations.

I love it!

My only recommendation is to add more material choices for SFM calculations. Ductile and grey iron would be ideal for me, why not also have titanium, bronze, brass, etc. excellent app and a must have shop aide!
