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	3	8	8
1	2	4	4
0	1	2	0
0	0	1	0

Add the last column: 8 + 4 = 12. So 1100₂ = 12₁₀.

In short: 1100₂: 1×8 = 8 → +1×4 = 12 → +0×2 = 12 → +0×1 = 12
