Simple. Easy to use

Material calculator has a clean easy face. It is easy to use and read. We have been using material calculator for over 10 years for our landscaping. I like that I can convert cubic feet to cubic yards and vice a versa and convert gallons to cubic measurement

Fantastic with one quibble

It’s a fantastic calculator for my needs and I use it constantly.

That said, other calculators in the Calculated Industries family can switch their orientation to landscape mode (on the iPad), this one doesn’t. It only has the one position, not even the reverse portrait mode (which would be useful on all devices). It’s a really useful feature that should make its way to this calculator.
