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
0	2	4	0
0	1	2	0
0	0	1	0

Add the last column: 8 = 8. So 1000₂ = 8₁₀.

In short: 1000₂: 1×8 = 8 → +0×4 = 8 → +0×2 = 8 → +0×1 = 8

How do you convert 1000 to decimal?
