Even though on the product's homepage it says this application is useful to people from the Oil & Gas community, I think the program comes in handy to any average computer users. For example, you can use the utility if you're checking a recipe online and wish to convert units (from Kg to Lbs).
In my testing, the program worked faultlessly and didn't slow down the performance of my Mac.
However, you can convert different units of measurement for the same quantity online, with a simple Google search in your default browser.
Cutting a long story short, this program proves to be a reliable solution when converting different units of measurement for the same quantity. The application is very simple to use and is free of charge. So, you have nothing to lose by trying it on your computer.
