Feet to Millimeters Calculator
Feet and mm (millimeters) measure length, but they belong to different systems. Feet are part of the imperial and U.S. customary systems, while millimeters belong to the metric system.
Many industries, such as construction, manufacturing, engineering, and textiles, require converting feet to millimeters for accurate measurements. Since 1 foot equals 304.8 mm, you can find millimeters by multiplying the number of feet by 304.8.
This article explains the conversion formula, provides examples, and highlights applications of feet to millimeters in different industries.
You can also solve your queries regarding yards to meters.

Formula for Feet to Millimeters
The formula to convert feet to millimeters is:
Millimeters= Feet×304.8
This means every foot contains 304.8 millimeters.
Example Calculation
Let’s convert 5 feet to millimeters:
5×304.8= 1524 mm
So, 5 feet = 1524 mm.
If you need to convert 10 feet:
10×304.8=3048 mm
Thus, 10 feet = 3048 mm.
Why Convert Feet to MM?
1. Construction and Architecture
Construction projects often use both imperial and metric units. Converting feet to millimeters ensures correct measurements for building materials, blueprints, and machine fittings.
For example, if a door frame measures 7 feet, the millimeter equivalent is:
7×304.8=2133.6 mm
2. Engineering and Manufacturing
Precision is crucial in engineering. Machines, tools, and components require millimeter accuracy. If a metal rod is 3.5 feet long, converting to millimeters helps in precise machining:
3.5×304.8=1066.8 mm
3. Textile and Fabric Measurement
Textile manufacturers and designers often work with millimeters for fabric width, thread spacing, and pattern sizing. A fabric roll that is 6 feet wide needs conversion for metric-based production:
6×304.8=1828.8 mm
4. Home Improvement and Interior Design
Furniture and fixtures are measured in both feet and millimeters. A 6-foot-long dining table converts to millimeters as follows:
6×304.8=1828.8 mm
5. Science and Medicine
Medical instruments, laboratory equipment, and scientific research often use millimeters. Converting feet to millimeters helps ensure proper calibration and measurement accuracy.

Step-by-Step Guide to Convert Feet to MM
Step 1: Identify the Feet Value
Determine the number of feet to convert.
Step 2: Multiply by 304.8
Since 1 foot = 304.8 mm, multiply the feet value by 304.8.
Step 3: Write the Result in Millimeters
The result is the total millimeters.
Example:
Convert 8 feet to millimeters:
8×304.8= 2438.4 mm
Thus, 8 feet = 2438.4 mm.
