Type a number in any box above.

Give each bit its place value — 1, 2, 4, 8 and so on, doubling from the right — then add up the places where the bit is 1.

Bit	Position	Place value	Bit × place
1	2	4	4
1	1	2	2
1	0	1	1

Add the last column: 4 + 2 + 1 = 7. So 111₂ = 7₁₀.

In short: 111₂: 1×4 = 4 → +1×2 = 6 → +1×1 = 7

How do you convert 111 to decimal?

Use place values. The 1 bits sit at place values 4, 2, 1, and 4 + 2 + 1 = 7. So 111₂ = 7₁₀.
