system, still widely used in the United States and a few other countries, divides length into a hierarchy of units. The most common small units are the <strong>foot<\/strong> (plural: feet) and the <strong>inch<\/strong>. One foot equals twelve inches. Both units are used for everyday measurements such as a person\u2019s height, the dimensions of furniture, or the size of a building component.<\/p>\n<h2 id=\"conversion-relationship\"><span class=\"ez-toc-section\" id=\"Conversion_Relationship\"><\/span>Conversion Relationship<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The relationship between feet and inches is fixed and linear:<\/p>\n<pre><code>1 foot = 12 inches<\/code><\/pre>\n<p>Because the ratio is constant, converting between the two units only requires multiplication or division by twelve.

The integer part of the quotient is the number of whole feet, and the remainder is the leftover inches:<\/p>\n<pre><code>Feet = floor(Inches \u00f7 12)\nRemaining inches = Inches mod 12<\/code><\/pre>\n<h2 id=\"practical-examples\"><span class=\"ez-toc-section\" id=\"Practical_Examples\"><\/span>Practical Examples<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"Example_1_Simple_Multiplication\"><\/span>Example 1: Simple Multiplication<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Convert 5 feet to inches.<\/p>\n<pre><code>Inches = 5 \u00d7 12 = 60 inches<\/code><\/pre>\n<p>The result is straightforward: 5\u202ffeet equals 60\u202finches.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Example_2_Mixed_Measurement\"><\/span>Example 2: Mixed Measurement<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Convert 7 feet\u202f9\u202finches to inches only.<\/p>\n<pre><code>Inches = (7 \u00d7 12) + 9 = 84 + 9 = 93 inches<\/code><\/pre>\n<p>Thus, 7\u202ffeet\u202f9\u202finches is the same as 93\u202finches.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Example_3_Converting_Back_to_Feet\"><\/span>Example 3: Converting Back to Feet<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Suppose a carpenter measures a board as 98 inches.
