Step by step
1. Divide by the base repeatedly
Divide 500 by 2 again and again, noting the remainder each time:
2. Collect the remainders
500 ÷ 2 = 250, remainder 0 · 250 ÷ 2 = 125, remainder 0 · 125 ÷ 2 = 62, remainder 1 · 62 ÷ 2 = 31, remainder 0 · 31 ÷ 2 = 15, remainder 1 · 15 ÷ 2 = 7, remainder 1 · 7 ÷ 2 = 3, remainder 1 · 3 ÷ 2 = 1, remainder 1 · 1 ÷ 2 = 0, remainder 1
3. Read the remainders bottom to top
Reading the remainders from bottom to top gives 111110100 — that is 500 in binary.

About number bases and place value
A number base (radix) defines how many digits are used and what each position is worth. Decimal uses ten digits and powers of ten, binary uses just two digits and powers of two, and hexadecimal uses sixteen digits and powers of sixteen.
The value itself never changes — only how it is written. These conversions are pure integer math and exact: 255 is always 0xFF.
Where hexadecimal shows up
Hex appears everywhere in computing: CSS color codes, memory addresses, MAC addresses, and byte values. One byte (8 bits) fits exactly into two hex digits (00–FF), i.e. 0 to 255.
Frequently asked questions
What is 500 in Binary?
500 in binary is 111110100 (0b111110100).
How do you convert 500 to binary?
Repeatedly divide 500 by 2 and read the remainders from bottom to top — that gives 111110100. The place-value table above shows each step.
What is 500 in binary and hexadecimal?
500 is 0b111110100 in binary and 0x1f4 in hexadecimal.
Why is hexadecimal used?
Hexadecimal (base 16) is compact: each hex digit maps to exactly four bits (one nibble). That is why color codes, memory addresses, and byte values are almost always written in hex — 255 is FF, far shorter than 11111111.
Are these conversions exact?
Yes. Converting between number bases is pure integer math and perfectly exact — the same value, just written a different way. 255 is always 0xFF.
