Mila Tools is an essential app in a world of multiple measurement standards

I encounter a variety of English Standard and Metric bolts and liquid measurements, and temperature settings. Given a tray full of wrenches, it helps to know that 13 mm and 19 mm are close enough to half inch and three quarters of an inch that the slightly larger will do the job. Recipes for volumes come in international measurements. With temperatures, Fahrenheit seems more precise but centigrade is useful for a wider range.
if an energy source provides BTU/hour, I can find the KW and HP potential which is useful in sizing and rating power generators.
I also appreciate the ability to use fractions within conversions.
So, I consider Mila’s Tools essential .

Super useful, spectacular app.

I am a journeyman elevator constructor. Our company uses the metric system for everything, including speed. The governing authority, in our case it’s the Indiana Department of Homeland Security wants everything in Imperial. I have to make detailed reports for both our company and the state, this app makes it painless. I have used this app for multiple years now and absolutely love it. The mm/s unit that was added on the last revision was at my request. I have all of my homey’s using it now also. Thank you very much Mr. Software Developer guy, as you have made my life easier. Every little bit helps.

This app is excellent. Been using it for years...

This app is excellent. Been using it for years whenever I need a conversion, be it temperature, distance, volume, rate of speed.. any conversion you could possibly need! Precise and very simple to use. This utility app would be in my top 15 easy. No complaints! I’d recommend Mila’s Tools app to anyone and everyone!! By the way, I hardly ever write app reviews, am a retired biologist, avid hiker, and enjoy cooking and trying recipes from other countries, most of which, use metric measurements. That is only three of the ways I use Mila’s Tools😊.
