249 in Binary

Decimal 249 in binary conversion provides the detailed information on what is the binary equivalent of (249)10, and the step-by-step work for how to convert the decimal (base-10) number 249 to its binary (base-2) equivalent.

(249)10 in binary is equal to:
(249)₁₀ = (?)₂
Perform successive MOD-2 operation for decimal 249, and mark the initial remainder as LSB and the final remainder as MSB as like the below.

249 MOD-2	249 / 2 = 124	Remainder is 1 → LSB
124 MOD-2	124 / 2 = 62	Remainder is 0
62 MOD-2	62 / 2 = 31	Remainder is 0
31 MOD-2	31 / 2 = 15	Remainder is 1
15 MOD-2	15 / 2 = 7	Remainder is 1
7 MOD-2	7 / 2 = 3	Remainder is 1
3 MOD-2	3 / 2 = 1	Remainder is 1
1 MOD-2	1 / 2 = 0	Remainder is 1 → MSB

Arrange the remainders from MSB to LSB forms the binary equivalent of 249.
249₁₀ = 11111001₂

Hence,
249 in binary is 11111001

where,
249₁₀ is the given decimal number,
10 in 249₁₀ represents the base-10 or decimal number system,
11111001₂ is the binary equivalent of the decimal 41,
2 in 11111001₂ represents the base-2 or binary number system.

Important Notes: (249)10 in Binary
