Decimal and Binary Numbering Systems: A Simple Guide

The decimal and binary numbering systems are two of the most common systems we use to count numbers. But, they work in different ways. Let’s explore these systems, their differences, and how to convert between them.

What is the Decimal Numbering System?

The decimal numbering system is the one most people use every day. It’s also known as the “denary” system. The word “decimal” comes from the Latin word “decimus,” meaning “tenth.” This system uses base ten, which means it includes the numbers from 0 to 9.

Every time you count, you start at 0 and go up to 9. When you reach 10, the system resets. So, after 9 comes 10, which is made up of a 1 in the “tens” place and a 0 in the “ones” place. This process keeps going, adding more places as needed. Here’s an example:

• 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13…

Each place value is ten times greater than the one before it. For example:

• 1, 10, 100, 1000, 10000…

This system is easy for most people to understand because we use it every day. It’s the most common system for everyday counting.

What is the Binary Numbering System?

The binary numbering system is very different. It is a system that only uses two numbers: 0 and 1. It’s called a “base-2” system because it only uses two digits.

In binary, every place value is a power of 2. For example:

• 1, 2, 4, 8, 16, 32, 64…

The numbers in the binary system look like this:

• 0, 1, 10, 11, 100, 101, 110, 111…

You can see that when we reach the number 2, it’s written as 10 in binary. The system then continues in powers of 2.

Why is binary important? It’s used by computers and digital systems to store and process data. Computers use binary because their circuits are either on (1) or off (0). This makes the binary system perfect for them.

Decimal to Binary Conversion

Sometimes, you may need to convert a decimal (base-10) number to binary (base-2). This process can seem a bit tricky if you don’t know how to do it.

One way to convert a decimal number to binary is by dividing the decimal number by 2. You write down the remainder of each division and keep dividing the quotient (the result of the division) by 2 until you reach 0. The binary number is then the remainders, read in reverse order.

Let’s look at an example. Suppose we want to convert the decimal number 13 to binary.

1. Divide 13 by 2. The quotient is 6, and the remainder is 1.
2. Divide 6 by 2. The quotient is 3, and the remainder is 0.
3. Divide 3 by 2. The quotient is 1, and the remainder is 1.
4. Divide 1 by 2. The quotient is 0, and the remainder is 1.

Now, we reverse the remainders. Starting from the last remainder to the first: 1101. So, 13 in decimal is 1101 in binary.

Why Use a Decimal to Binary Calculator?

The process of manually converting decimal numbers to binary can be slow and sometimes confusing. It involves several steps, and if you make a mistake, it can be hard to find where you went wrong. That’s why a decimal to binary calculator is so helpful.

With a calculator, you can convert decimal numbers to binary quickly and accurately. All you need to do is enter the decimal number, and the calculator will do the rest.

Using an Online Decimal to Binary Converter

Converting Decimal Fractions to Binary

Sometimes, you may need to convert decimal fractions to binary. This process is slightly different from converting whole numbers. To convert a decimal fraction to binary, you multiply the fraction by 2 and write down the whole number part. You then repeat the process with the fractional part until you get a result.

Let’s take an example. Suppose we want to convert the decimal fraction 0.625 to binary.

1. Multiply 0.625 by 2. The result is 1.25. The whole number part is 1.
2. Multiply 0.25 by 2. The result is 0.5. The whole number part is 0.
3. Multiply 0.5 by 2. The result is 1.0. The whole number part is 1.

Now, we read the whole number parts in order: 101. So, 0.625 in decimal is 0.101 in binary.

Conclusion

Understanding the decimal and binary numbering systems is important, especially if you work with computers or digital technologies. The decimal system is the one we use in everyday life, while the binary system is used by computers to process data.

Converting between the two systems can be tricky, but with the help of a decimal to binary calculator, you can make the process much easier and faster. At Nixtool, we offer a simple, reliable, and free tool to help you convert decimal numbers to binary accurately and quickly.
