How to convert binary to hexadecimal and back again (very simple shortcut)

5 stars based on 43 reviews

The hexadecimal numeral systemalso known as just hexis a numeral system made up of 16 symbols base The standard numeral system is called decimal base 10 and uses ten symbols: Hexadecimal uses the decimal numbers and includes six extra symbols.

There are no symbols that mean ten, or eleven etc. Humans mostly use the decimal system. This is probably because humans have ten fingers ten digits. Computers however, only have on and off, called a binary digit or bit, for short. A binary number is just a string of zeros and ones: For convenience, engineers working with computers tend to group bits together. In earlier days, such as the 's, they would group 3 bits at a time much like large decimal numbers are convert binary and hexadecimal value in threes, like the number , Three bits, each being on or off, can represent the eight numbers from 0 to 7: This is called octal.

As computers got bigger, it was more convenient to convert binary and hexadecimal value bits by four instead of three. This doubles the numbers that the symbol would represent; it can have 16 values instead of eight. Four bits is called a nibble sometimes spelled nybble. A nibble is one hexadecimal digit, and is written using a symbol or A-F. Two nibbles is a byte 8 bits.

Most computer operations use the byte, or a multiple of the byte 16 bits, 24, 32, 64, etc. Hexadecimal makes it easier to write these large binary numbers. To avoid confusion convert binary and hexadecimal value decimal, octal or other numbering systems, hexadecimal numbers are sometimes written with a "h" after the number. For example, 63h means 63 hexadecimal. Software developers quite often use 0x before the number 0x Hexadecimal is similar to the octal numeral system base 8 because each can be easily convert binary and hexadecimal value to the binary numeral system.

Hexadecimal uses a four- bit binary coding. This means that each digit in hexadecimal is the same as four digits in binary. Octal uses a three-bit binary system. In the decimal system, the first digit is the one's place, the next digit to the left is the ten's place, the next is the hundred's place, etc.

In hexadecimal, each digit can be 16 values, not This convert binary and hexadecimal value the digits have the one's place, the sixteen's place, and the next one is the 's place. Changing a number convert binary and hexadecimal value binary to hex uses a grouping method. The binary number is separated into groups of four digits starting from the right. These groups are then converted to hexadecimal digits as shown in the chart above for the hexadecimal numbers 0 through F.

To change from hexadecimal, the reverse is done. The hex digits are each changed to binary and the grouping is usually removed. The next method is more commonly done when converting a number in software.

It doesn't need to know how many digits the number has before it starts, and it never multiplies by more than 16, but it looks longer on paper. From Wikipedia, the free encyclopedia.

It's also called base-2 number system only uses 0 and 1 to represent any sort of information. Besides, the step by step calculation along with solved example problem let the users easily understand how manually perform such conversions. The rightmost digit of the binary number has the weightage of 2 0 and the power of 2 will increase by 1 for each successive digit from right to left see the solved example below. It's also called as the place value of binary digits. Step by step conversion: Multiply the binary digit with place value for each digit.

Sum all the product values provides an equivalent decimal. The below solved example let the users to know how to convert fractional binary number Binary to Hex Conversion Binary to Hex conversion can be done by divide the bits into groups from right to left side, each containing 4 bits.

If the group is lack of 4 bits then add 0 or 0s to the left hand side to make sure each group containing 4 bits. The extra bits of 0 at the left side are called padding. The below solved example let the users to understand how to convert binary to decimal number. Split the given binary number into groups from right, each containing 4 bits.

Add 0 or 0s to the left side if any group is lack of 4 bits. Find the Hex equivalent for each group. Form the each group Hex number together in the same order. Binary to Octal Conversion Binary to Octal conversion can be done by divide the bits into groups from right to left side, each containing 3 bits. If the group is lack of 3 bits then add 0 or 0s to the left hand side to make sure each group containing 3 bits.

The below solved example let the users to understand how to convert binary to octal number. Split the given binary number into groups from right, each containing 3 bits.

Add 0 or 0s to the left side if any group is lack of 3 bits. Find the Octal equivalent for each group. Form the each group Octal number together in the same order.
