The number system is a way to represent numbers using a collection of symbols and guidelines. The most commonly used number system is the decimal number system, which has base 10 and uses ten digits 0 to 9 to form other numbers.<\/p>\n\n\n\n<p class=\"eplus-wrapper\">Here\u2019s a chart showing different number systems and the number of digits used in each system.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full eplus-wrapper\"><img loading=\"lazy\" decoding=\"async\" width=\"512\" height=\"444\" src=\"https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2024\/06\/types-of-number-systems.png\" alt=\"Types of number systems\" class=\"wp-image-42119\" title=\"Types of number systems\" srcset=\"https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2024\/06\/types-of-number-systems.png 512w, https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2024\/06\/types-of-number-systems-300x260.png 300w\" sizes=\"auto, (max-width: 512px) 100vw, 512px\" \/><\/figure>\n\n\n\n<p class=\"eplus-wrapper\">The octal numeral system is the base-8 number system, and uses the digits 0 to 7. That means there are only 8 symbols or digits (0, 1, 2, 3, 4, 5, 6, 7) used to form other numbers.<\/p>\n\n\n\n<p class=\"eplus-wrapper\">The main advantage of using the octal number system is that it uses fewer digits than the decimal and hexadecimal number system. So, it has fewer calculations and thereby less calculation errors.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading eplus-wrapper\" id=\"1-definition-of-octal-number-system\">Definition of Octal Number System<\/h3>\n\n\n\n<p class=\"eplus-wrapper\"><strong>A number system with base 8 is called an octal number system. The position of every digit has a value which is a power of 8. A number in the octal number system is represented with the number 8 at the base, like <\/strong>$512_8,\\; 56_8$<strong>, etc.<\/strong><\/p>\n\n\n\n<p class=\"eplus-wrapper\">Now let us understand how the interconversions between these systems are done.<\/p>\n\n\n\n<div id=\"recommended-games-container-id\" class=\"recommended-games-container\"><h4

class=\"wp-block-heading eplus-wrapper\" id=\"2-conversion-of-octal-to-binary-numbers\">Conversion of Octal to Binary Numbers<\/h2>\n\n\n\n<p class=\"eplus-wrapper\">The base of the octal number system is 8. The base of the binary number system is 2. To convert octal to binary, we need to convert each number from the octal number to the binary number. Take a look at the octal to binary conversion table given below:<\/p>\n\n\n\n<figure class=\"wp-block-table eplus-wrapper\"><table class=\"wj-table-class\"><tbody><tr><td class=\"has-text-align-center\" data-align=\"center\"><strong><em>Octal Value<\/em><\/strong><\/td><td class=\"has-text-align-center\" data-align=\"center\"><strong><em>Binary Equivalent<\/em><\/strong><\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\">0<\/td><td class=\"has-text-align-center\" data-align=\"center\">000<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\">1<\/td><td class=\"has-text-align-center\" data-align=\"center\">001<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\">2<\/td><td class=\"has-text-align-center\" data-align=\"center\">010<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\">3<\/td><td class=\"has-text-align-center\" data-align=\"center\">011<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\">4<\/td><td class=\"has-text-align-center\" data-align=\"center\">100<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\">5<\/td><td class=\"has-text-align-center\" data-align=\"center\">101<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\">6<\/td><td class=\"has-text-align-center\" data-align=\"center\">110<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\">7<\/td><td class=\"has-text-align-center\" data-align=\"center\">111<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"eplus-wrapper\">Every digit has to be converted to a 3-bit binary number. Thus, we get the binary equivalent of the number. Let\u2019s understand this with the help of an example.<\/p>\n\n\n\n<p class=\"eplus-wrapper\"><strong>Example: Convert <\/strong>$(16)_8$<strong> into a binary number.<\/strong><\/p>\n\n\n\n<p class=\"eplus-wrapper\"><strong>Solution:<\/strong> $(16)_8$ is an octal number.<\/p>\n\n\n\n<p class=\"eplus-wrapper\">With the help of the above conversion table, we can write<\/p>\n\n\n\n<p class=\"eplus-wrapper\">&nbsp;$1_8 = 001_2$ and $6_8 = 110_2$<\/p>\n\n\n\n<p class=\"eplus-wrapper\">Thus, $(16)_8 = (001110)_2$<\/p>\n\n\n\n<div id=\"recommended-worksheets-container-id\"

of Octal to Decimal Numbers<\/h2>\n\n\n\n<p class=\"eplus-wrapper\">Converting octal to decimal is a simple process!<\/p>\n\n\n\n<p class=\"eplus-wrapper\">A number in the octal system is expanded with the base of eight, where each digit is multiplied with the power of 8, based on its position.&nbsp;<\/p>\n\n\n\n<p class=\"eplus-wrapper\">After the octal is converted to decimal, it has a base of 10.<\/p>\n\n\n\n<p class=\"eplus-wrapper\">Let us understand this with the help of an example:<\/p>\n\n\n\n<p class=\"eplus-wrapper\"><strong>Example: Convert <\/strong>$(321)_8$<strong> to decimal form.<\/strong><\/p>\n\n\n\n<p class=\"eplus-wrapper\"><strong>Solution:&nbsp;<\/strong><\/p>\n\n\n\n<p class=\"eplus-wrapper\">&nbsp;$(321)_8 = (3\\times8^2) + (2\\times8^1) +

He suggested the base 8 and he coined the term octal.<\/li>\n<\/ul>\n\n\n\n<ul class=\"eplus-wrapper wp-block-list\">\n<li class=\"eplus-wrapper\">The main advantage of using octal numbers is that it uses fewer digits than the decimal and hexadecimal number system. So, it has fewer computations and less computational errors.&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"eplus-wrapper wp-block-list\">\n<li class=\"eplus-wrapper\">The octal number system is widely used in computer application sectors and digital numbering systems. The octal number is also used in the aviation sector in the form of a code.<\/li>\n<\/ul>\n\n\n\n<ul class=\"eplus-wrapper wp-block-list\">\n<li class=\"eplus-wrapper\">The octal system is similar to the hexadecimal system because they are both easily converted to binary, where octal is equal to three-digit binary and hexadecimal is equal to four-digit binary.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading eplus-wrapper\" id=\"8-conclusion\">Conclusion<\/h2>\n\n\n\n<p class=\"eplus-wrapper\">In this article, we have learned about the octal number system and the interconversions between octal, binary, hexadecimal, and decimal.

provides a convenient way of converting large binary numbers into more compact and smaller groups.
