Convert height or length from feet and inches to total inches.
Need to convert a height or length given in feet and inches to total inches? You're in the right place. This guide will help you easily convert values like 5 feet 8 inches to just inches. This is especially useful for construction professionals, designers, engineers, athletes, and anyone who needs precise measurement inputs in one single unit.
Measurements are often given in feet and inches, especially in the United States and the UK. However, for accuracy, comparison, or data input in calculators, 3D software, or spreadsheets, you often need to combine them into a single unit: inches.
For example:
The formula is simple and requires only basic multiplication and addition:
Total Inches = (Feet × 12) + Inches
Because 1 foot = 12 inches. So, converting feet to inches means multiplying by 12 and then adding the remaining inches.
Convert 5 feet 9 inches to inches:
= (5 × 12) + 9
= 60 + 9 = 69 inches
Convert 6 feet 1 inch to inches:
= (6 × 12) + 1
= 72 + 1 = 73 inches
Convert 4 feet 11 inches to inches:
= (4 × 12) + 11
= 48 + 11 = 59 inches
| Feet | Inches | Total Inches |
|---|---|---|
| 4 | 0 | 48 |
| 4 | 6 | 54 |
| 5 | 0 | 60 |
| 5 | 5 | 65 |
| 5 | 8 | 68 |
| 6 | 0 | 72 |
| 6 | 4 | 76 |
| 6 | 8 | 80 |
This conversion is used across many fields and practical situations:
Height is often written as 5’6”, but BMI calculators and fitness software require a single unit like inches or cm.
When creating blueprints or floorplans, measurements must be in a consistent unit for precision. Many CAD tools accept only inches or metric units.
Whether you’re buying curtains, building furniture, or measuring space, inches are easier for accurate purchasing and design.
Tailors and designers may ask for your height or length in inches for fittings or production.
Interior dimensions of aircraft, car components, or seats may require input in inches for calculation tools.
You can save time and reduce mistakes by using our Feet+Inches to Inches converter tool. Just input the number of feet and inches, click "Convert", and instantly get the result in inches.
If you have a total inches value and want to convert it back into feet and inches:
Convert 67 inches to feet and inches
67 ÷ 12 = 5 feet and 7 inches (since 12×5 = 60, remainder = 7)
(5 × 12) + 10 = 60 + 10 = 70 inches
(6 × 12) + 2 = 74 inches
Yes! Use the formula: = (feet_cell * 12) + inches_cell
Absolutely. Many forms, apps, and health trackers need height in inches instead of ft+in format.

An inch, symbolized as in, is one of the most recognized and commonly used units of length in the United States, Canada, and the United Kingdom. Though the metric system has become the global standard in most countries, inches are still used in various fields including construction, design, screen sizes, tools, and daily life. In this comprehensive guide, we’ll explore what inches are, their history, how they compare with metric units, conversion formulas, real-life uses, and frequently asked questions.
An inch is a unit of length in the Imperial and U.S. customary measurement systems. It is defined as exactly:
The inch is abbreviated as in or marked with a double prime symbol (″). For example, 6 inches can be written as 6 in or 6″.
The word "inch" originates from the Latin word uncia, meaning a one-twelfth part. Historically, the inch was defined based on the width of a human thumb or three grains of barley placed end to end.
In 1959, countries such as the United States and members of the Commonwealth agreed to standardize the inch as exactly 2.54 centimeters—known as the “international inch.”
in × 2.54 = cmin × 25.4 = mmin × 0.0254 = min ÷ 12 = ftTVs, monitors, and mobile devices list screen sizes in inches, measured diagonally from one corner of the screen to the opposite corner.
Inches are used to measure wood, piping, metal, nails, bolts, and other materials. It allows for precise yet practical dimensions in construction and remodeling.
Wrenches, screwdrivers, drill bits, and fasteners are often measured in inches, especially in regions that follow the Imperial system.
Waist sizes, collar sizes, and inseams are often measured in inches. For example, men’s jeans might say “34x30,” meaning a 34-inch waist and 30-inch leg length.
Page dimensions, photo sizes, and posters are often measured in inches, such as 8.5"x11" paper size (standard U.S. letter).
While most of the world uses centimeters due to the metric system, inches are still the standard in the U.S., especially in industries like manufacturing and engineering.
Understanding both systems is essential for global compatibility and technical precision.
Inch rulers are divided into small segments. Most rulers in the U.S. divide each inch into 16 or 32 smaller parts.
This allows users to measure very small dimensions accurately, which is crucial in carpentry and machining.
In math problems, inches are used to calculate length, area, and volume:
12 inches make up 1 foot.
Use the formula: cm × 0.3937 = inches. For example, 10 cm × 0.3937 ≈ 3.937 in.
It is a longstanding convention in electronics, and the diagonal measurement gives a standardized size across models.
No. Inch belongs to the Imperial and U.S. customary systems, not the metric system.
| Inches | Centimeters | Millimeters | Feet |
|---|---|---|---|
| 1 in | 2.54 cm | 25.4 mm | 0.083 ft |
| 5 in | 12.7 cm | 127 mm | 0.417 ft |
| 12 in | 30.48 cm | 304.8 mm | 1 ft |
| 24 in | 60.96 cm | 609.6 mm | 2 ft |
| 36 in | 91.44 cm | 914.4 mm | 3 ft |
| 72 in | 182.88 cm | 1828.8 mm | 6 ft |
