How to Convert Decimal to Binary
Converting decimal numbers to binary is a key concept in computer science and digital electronics. It bridges the gap between human-readable numbers (decimal) and machine-level data (binary), making it essential for understanding how computers process and store information.
A Decimal to Binary Converter automates this transformation, instantly converting base-10 numbers into binary code. It's a helpful tool for developers, students, and anyone working with digital systems or learning programming fundamentals.
What Is Decimal to Binary Conversion?
Decimal to binary conversion means changing a number from base 10, which uses digits 0 to 9, to base 2, which uses only 0 and 1. The binary system represents values using powers of 2 and is the core of all computing processes.
This conversion is essential because digital devices operate using binary signals—on (1) and off (0). Translating decimal to binary is crucial for tasks like memory management, networking, and coding.
How Does a Decimal to Binary Converter Work?
A Decimal to Binary Converter takes a decimal input and divides it repeatedly by 2, recording the remainder each time. The binary number is formed by reading the remainders in reverse order, from last to first.
The converter performs these steps instantly, ensuring accurate results and saving time, especially when converting large numbers or performing multiple conversions.
Formula to Convert Decimal to Binary
To convert a decimal number (D) to binary:
-
Divide D by 2.
-
Write down the remainder (0 or 1).
-
Divide the quotient by 2 again.
-
Repeat until the quotient is zero.
-
Read the remainders from bottom to top.
Example: Convert 13 to binary
13 ÷ 2 = 6, remainder 1
6 ÷ 2 = 3, remainder 0
3 ÷ 2 = 1, remainder 1
1 ÷ 2 = 0, remainder 1
Result: 1101
Examples of Decimal to Binary Conversion
Check out the conversion table below:
Decimal | Binary |
---|---|
1 | 1 |
2 | 10 |
5 | 101 |
10 | 1010 |
16 | 10000 |
31 | 11111 |
64 | 1000000 |
These examples show how decimal values translate into binary format, crucial for understanding digital systems.

Frequently Asked Questions
What is the binary system?
The binary system is a base-2 number system that uses only the digits 0 and 1. It’s the language of computers, representing data as electrical signals—on (1) and off (0).
How do you manually convert decimal to binary?
Divide the decimal number by 2 repeatedly, writing down the remainders. When the quotient reaches zero, read the remainders from bottom to top to get the binary value.
Why is decimal to binary conversion important?
It helps translate human-readable numbers into a format computers can understand and use. This is critical in programming, networking, and digital design.
Can negative decimal numbers be converted to binary?
Yes, but they use a special representation called two's complement in binary. Most converters only handle positive integers unless otherwise specified.
What if I enter a non-integer in the converter?
Basic converters may only work with integers. More advanced tools can handle floating-point conversions by separating the integer and fractional parts and applying appropriate binary rules to each.
