􀂉 Know the weight of each bit in a binary
number
􀂉 Add them together to get its decimal
equivalent

Ex. Convert 110012 to decimal
Weight: 2^4 2^3 2^2 2^1 2^0
Digits: 1         1      0    0     1
Sum: 16 + 8 + 0 + 0 + 1 = 2510

Use the concept of weight to convert a
decimal number to a binary directly
