To convert 1 foot to inch, multiply the value in feet by the conversion factor of 12.000000. So, 1 foot × 12.000000 = 12.0000 inch.

1 foot equals exactly 12.000000 inch. For practical applications, this is often expressed as 12.0000 inch.

Objects measuring approximately 1 foot include a Westcott 12-inch Wooden Ruler (1.00 foot or 12.0 inches), a Kellogg's Frosted Flakes Cereal Box (1.00 foot or 12.0 inches tall), and an Apple MacBook Air 13-inch (M2) which is 0.99 foot or 11.97 inches wide.

Converting foot to inch is useful for detailed measurements in construction, interior design, and DIY projects where finer precision than feet is required. It aligns with common tool markings and regional standards in the United States, facilitating clear communication and accurate execution.

A simple memory aid is to visualize a standard 12-inch ruler, which is exactly 1 foot long. Another technique is to remember that there are 12 months in a year, similar to 12 inches in a foot, making the number 12 easy to recall for this conversion.
