Examples

Octal to Decimal Conversion

Octal to decimal conversion can be made through summation of multiplication of each digit with increasing power of 8 from the right to left of the binary number. Refer this below workout to understand how to convert base-8 octal to base-10 decimal number, or use this octal calculator to easily find out the decimal equivalent for a given octal number.

Example :
Find the decimal equivalent for octal 6342₈
              = (2 x 8⁰) + (4 x 8¹) + (3 x 8²) + (6 x 8³)
              = (2 x 1) + (4 x 8) + (3 x 64) + (6 x 512)
              = 2 + 32 + 192 + 3072
              = 3298₁₀
The decimal equivalent for octal 6342₈ is 3298₁₀

Use this octal to decimal converter calculator for quick conversions, arithmetic operations and to generate the complete step by step work for such conversions.

Octal to Binary Conversion

Octal to binary conversion can be made by arranging the 3-digit binary equivalent of a given octal number in the same order as the binary equivalent. Refer this below workout to understand how to convert base-8 octal to base-2 binary number, or use this octal calculator to easily find out the binary equivalent for a given octal number.

Example :
Find the binary equivalent for octal 736₈

Write each digit of octal number into its equivalent binary containing 3 digits each.
7 = 111 3 = 011 6 = 110
Arrange the binary numbers group in the same order.
111011110

The binary equivalent for octal 736₈ is 111011110₂

Use this octal to binary converter calculator for quick conversions, arithmetic operations and to generate the complete step by step work for such conversions.

Octal to Hex Conversion

The octal to hex conversion can be made by writing the each digit of given octal number into its equivalent 3-digit binary number, arrange them in the same order, splitting it into groups each containing 4-binary digits, then finding the equivalent hex values for each group and arranging them in a same order would provide the hex equivalent. Refer this below workout to understand how to convert base-8 octal to base-16 hexadecimal number, or use this octal calculator to easily find out the hexadecimal equivalent for a given octal number.

Example :
Find the hex equivalent for octal 675₈
Write the each digit of given octal number into its equivalent 3 digit binary number.
     6 = 110      7 = 111       5 = 110

Arrange them in the same order
110111110

Split the binary number into groups each containing 4 binary digits.
0001      1011      1110

Find the equivalent hex values for each group.
0001 = 1     1011 = B     1110 = E

Arranging them in a same order would provide the hex equivalent
1BE
The hex equivalent for octal 675₈ is 1BE₁₆

Use this octal to hex converter calculator for quick conversions, arithmetic operations and to generate the complete step by step work for such conversions.
