Very useful, thanks! ### 5/5 — 1010000001110101110 *2018-05-18, version 2.0.7* That's "nice" in binary. This is a good app! ### 4/5 — Simple, useful. *2015-08-13, version 2.0.6* Simple to use, does what it says, although I'm struggling to see how to convert other than decimal to, e.g binary. ### 5/5 — Works as advertised! *2015-07-04, version 2.0.6* Been studying how to convert IP Addresses to Binary. Verifying my work with this app and it works terrific. Quick, easy and accurate! ### 5/5 — Rz *2014-05-01, version 2.0.3* Nice app! ### 5/5 — Just right *2014-02-19* Many more features and better presented than any of the others. ### 3/5 — No letters *2012-10-19, version 1.4* It converts from decimal great, but it lacks the ability to enter letters in anything base eleven or higher. ### 4/5 — Works great *2012-09-15, version 1.4* An improvement would be the ability to enter something other than decimal in upper register so you could directly convert hex to binary, etc. ### 5/5 — Awesome. It just works. That's it. *2012-08-28* This is exactly what I need. ## Frequently asked questions about Binary Calc ### What can this calculator do?
