Feet to Inches Converter
The feet to inches converter makes it simple to switch between these two imperial length units in seconds. It saves time and prevents errors across construction, medical records, and interior design. Enter any value in feet and get the exact result in inches instantly.
This feet and inches calculator is useful any time you need a quick length conversion between imperial measurement units. It handles both simple feet values and combined feet-and-inches inputs, practical for height measurement and other measurement units needs. Feet and inches are both part of the US customary and imperial measurement systems. The National Institute of Standards and Technology (NIST) defines one foot as exactly 0.3048 meters and one inch as exactly 2.54 centimeters. These definitions have been standardized internationally since 1959. The United States is one of only three countries — alongside Liberia and Myanmar — that still use feet and inches as primary units. This represents over 335 million daily users of the imperial system.
How to Convert Feet to Inches
Converting feet to inches uses one simple rule: multiply the number of feet by 12. If you have ever asked how many inches in a foot, the answer is always 12 — this is the foundation of every feet-to-inches conversion. Put another way: 1 foot in inches = 12, and 1 feet in inches = 12. Both phrases refer to the same unit.
Formula: Inches = Feet x 12
If your measurement includes both feet and inches, multiply the feet by 12, then add the remaining inches.
Formula: Total inches = (Feet x 12) + Inches
Example 1: Convert 3 feet to inches: 3 x 12 = 36 inches
Example 2: Convert 5 feet 9 inches to inches: (5 x 12) + 9 = 60 + 9 = 69 inches
Example 3: Convert 10 feet to inches: 10 x 12 = 120 inches
To reverse the calculation, dividing inches by 12 converts back to feet. For example, 84 inches divided by 12 equals 7 feet.
6 Feet to Inches
6 feet equals 72 inches. The calculation: 6 x 12 = 72.
6 feet is a widely referenced height in sports, medicine, and everyday conversation. A person who is 6 feet tall stands at exactly 72 inches, or approximately 182.88 centimeters. In the NBA, 6 feet is close to the average height for a point guard. In construction, a standard interior door in the United States is 80 inches tall, just 8 inches more than 6 feet.
| Feet | Inches |
|---|---|
| 6 ft 0 in | 72 inches |
| 6 ft 1 in | 73 inches |
| 6 ft 2 in | 74 inches |
| 6 ft 3 in | 75 inches |
| 6 ft 4 in | 76 inches |
| 6 ft 6 in | 78 inches |
5 Feet to Inches
5 feet equals 60 inches. The calculation: 5 x 12 = 60.
5 feet is a common height reference point in many contexts. In the United States, the average height for adult women is around 5 feet 4 inches, which equals 64 inches. A 5-foot ceiling height would be unusually low as most residential rooms have ceilings between 8 and 9 feet. In track and field, the women high jump world record is over 6 feet 8 inches, making 5 feet a useful reference for comparison.
| Feet | Inches |
|---|---|
| 5 ft 0 in | 60 inches |
| 5 ft 1 in | 61 inches |
| 5 ft 2 in | 62 inches |
| 5 ft 3 in | 63 inches |
| 5 ft 4 in | 64 inches |
| 5 ft 6 in | 66 inches |
| 5 ft 8 in | 68 inches |
| 5 ft 10 in | 70 inches |
5 Feet 6 Inches in Inches
5 feet 6 inches equals 66 inches. The calculation: (5 x 12) + 6 = 60 + 6 = 66.
5 feet 6 inches is the average height for women in several countries, including the United Kingdom. In fashion, 5 feet 6 inches is the standard height used for clothing size 8 to 10 in international sizing charts. When converting 5 feet 6 inches to centimeters, multiply 66 inches by 2.54 to get 167.64 cm. To find any mixed feet-and-inches measurement in total inches, always multiply the feet portion by 12 first, then add the leftover inches.

What Is a Foot?
A foot is a unit of length in the US customary and imperial measurement systems. One foot equals 12 inches, or exactly 0.3048 meters. The foot is abbreviated as ft. It is widely used in the United States, Canada, and the United Kingdom for height, room dimensions, elevation, and aviation distances.
In 1959, an international agreement standardized the foot. The US, UK, Australia, Canada, New Zealand, and South Africa aligned their definitions to the same metric equivalent.
A common question is: 1 foot is how many inches? The answer is exactly 12. Equally, 1 feet is equal to how many inches — 12. And 1 foot equals how many inches in the US customary system — still 12. No matter how the question is phrased, the relationship never changes.
What Is an Inch?
An inch is a unit of length equal to 1/12 of a foot, or exactly 2.54 centimeters. The inch is abbreviated as in. It is commonly used for measuring screen sizes such as televisions and monitors, clothing dimensions, pipe diameters, and tire widths.
The term inch comes from the Latin word uncia, meaning one-twelfth. Historically, an inch was based on the width of a human thumb. Today it is precisely defined as 25.4 millimeters under standards maintained by NIST and equivalent bodies worldwide.
Real-World Applications
Converting between feet and inches comes up in many everyday situations:
- Construction and renovation: A standard US ceiling height of 8 feet equals 96 inches. Lumber is sold in lengths like 8 ft (96 in), 10 ft (120 in), and 12 ft (144 in). Getting the feet to inches conversion right prevents costly cutting errors on the job site.
- Medical records: Height is recorded in feet and inches in the US, but total inches or centimeters are needed for BMI calculations and international records. A patient who is 5 feet 10 inches tall is 70 inches, which converts to 177.8 cm.
- Interior design: Standard doorframes are 80 inches tall (6 ft 8 in), and window dimensions are specified in mixed feet and inches. Converting to total inches makes it easier to order materials and verify clearances.
- Sports: In basketball, the regulation hoop height is 10 feet or 120 inches. In American football, a first-down gain of 10 yards equals 30 feet or 360 inches. In swimming, an Olympic pool is 50 meters, approximately 164 feet or 1,968 inches.
- Screen sizes: Television and monitor sizes are measured diagonally in inches. A 65-inch TV is just over 5 feet 4 inches diagonally. Knowing the feet to inches relationship helps when planning room layouts around entertainment setups.
Limitations of This Converter
- This converter handles linear measurement only. It does not calculate area (square feet to square inches requires multiplying by 144) or volume (cubic feet to cubic inches requires multiplying by 1,728).
- For measurements requiring fractional inch precision such as 1/8 or 1/16 inch, enter the decimal equivalent. For example, 1/8 inch equals 0.125 inches.
- This tool converts within US customary and imperial units. To convert to metric units, use our cm to feet converter or mm to inches converter.
- Decimal feet such as 5.75 feet produce exact inch results: 5.75 x 12 = 69 inches. This is not the same as 5 feet 75 inches, which is not a valid mixed measurement.
Feet and Inches to Inches — Combined Measurements
Many real-world measurements are given in a combination of feet and inches rather than purely in feet or purely in inches. Converting these combined values to total inches requires two steps: first multiply the feet by 12, then add the inch remainder.
Here are common combined measurements converted to total inches:
| Measurement | Calculation | Total Inches |
|---|---|---|
| 4 ft 6 in | (4 x 12) + 6 | 54 inches |
| 5 ft 3 in | (5 x 12) + 3 | 63 inches |
| 5 ft 6 in | (5 x 12) + 6 | 66 inches |
| 5 ft 9 in | (5 x 12) + 9 | 69 inches |
| 6 ft 1 in | (6 x 12) + 1 | 73 inches |
| 6 ft 4 in | (6 x 12) + 4 | 76 inches |
| 6 ft 8 in | (6 x 12) + 8 | 80 inches |
| 7 ft 6 in | (7 x 12) + 6 | 90 inches |
This method works for any combination. Handle the feet portion first, then add the inches. A common error: 5 feet 9 inches is 69 inches, not 59 inches.
How to Use a Feet to Inches Conversion Chart
A feet to inches conversion chart is a quick-reference tool for situations where you need to convert multiple measurements without recalculating each time. Carpenters, interior designers, and architects often keep a printed or digital chart nearby to speed up their work.
To use the chart: find your value in feet in the left column, then read the corresponding inches in the right column. For mixed measurements like 3 feet 7 inches, find 3 feet (36 inches) in the chart, then add 7 manually to get 43 inches.
Digital converters replace the chart for everyday use. A printed inches to feet chart is still useful offline on a job site or in a classroom.
