One square foot is 12 inches \u00d7 12 inches = 144 square inches. When you multiply two inch measurements together, you get square inches \u2014 so you need to divide by 144 to get square feet. Dividing by 12 only converts one dimension, not both.<\/p>\n  <\/div>\n  <div class=\"faq-item\">\n    <div class=\"faq-q\">What is 120 inches \u00d7 144 inches in square feet?<\/div>\n    <p class=\"faq-a\">120 \u00d7 144 = 17,280 square inches. 17,280 \u00f7 144 = 120 square feet. That&#8217;s the same as a 10 ft \u00d7 12 ft room.<\/p>\n  <\/div>\n  <div class=\"faq-item\">\n    <div class=\"faq-q\">Can I convert each measurement to feet first, then multiply?<\/div>\n    <p class=\"faq-a\">Yes \u2014 that&#8217;s Method 2 above and it gives the same answer. Divide each inch measurement by 12 to get feet, then multiply length \u00d7 width. Both methods are equally correct.<\/p>\n  <\/div>\n  <div class=\"faq-item\">\n    <div class=\"faq-q\">What if my measurements aren&#8217;t whole inches \u2014 like 126.5 inches?<\/div>\n    <p class=\"faq-a\">Use the decimal as-is. 126.5 \u00d7 108 = 13,662 \u00f7 144 = 94.9 sq ft. The formula handles decimals the same way as whole numbers \u2014 just multiply and divide.<\/p>\n  <\/div>\n  <div class=\"faq-item\">\n    <div class=\"faq-q\">Is it more accurate to measure in inches than in feet?<\/div>\n    <p class=\"faq-a\">Not more accurate \u2014 but for small rooms or areas where inch-level precision matters (tile work, small bathrooms), measuring in total inches avoids the step of converting feet and inches to decimal feet. The precision of the result depends on how carefully you measure, not on which unit you use.<\/p>\n  <\/div>\n  <div class=\"faq-item\">\n    <div class=\"faq-q\">How many square inches are in a square foot?<\/div>\n    <p class=\"faq-a\">144 square inches. A square foot is a 12-inch \u00d7 12-inch square, and 12 \u00d7 12 = 144.
