Insert a base 10 number (normal numbers) and it will convert it into a binary number. Try it! if you compare it to convertors online it matches perfectly i've tried up to 7979793451083 so far. :) [Online convertors will say Binary to decimal or base 10, (they're the same thing)] Binary to base 10 is out! Type a series of 1's and 0's and the computer will translate it into base 10! just click the button for 10:2 is base 10-binary and 2:10 is binary-base 10! Press space to reset and then click another one.
Update: Added a list so that you can copy and paste the binary number to check it online. Just double click the list number even if the whole thing doesn't show up.
