Conversion Examples
Example: Convert 1 foot to millimeters
- Step 1: Identify the conversion factor. Since 1 foot = 304.8 millimeters, multiply feet by 304.8.
- Step 2: Multiply 1 foot by 304.8.
- Step 3: 1 × 304.8 = 304.8 millimeters
1 foot = 304.8 millimeters
This is the fundamental conversion, showing that 1 foot equals exactly 304.8 millimeters by international standard.
Example: Convert 2.5 feet to millimeters
- Step 1: Use the conversion factor: 1 foot = 304.8 millimeters.
- Step 2: Multiply 2.5 feet by 304.8.
- Step 3: 2.5 × 304.8 = 762 millimeters
2.5 feet = 762 millimeters
This demonstrates converting a common measurement, often used in manufacturing and engineering specifications.
Example: Convert 5 feet to millimeters
- Step 1: Conversion factor: 1 foot = 304.8 millimeters.
- Step 2: 5 feet × 304.8
- Step 3: Result = 1,524 millimeters
5 feet = 1,524 millimeters
This shows converting a longer measurement, useful for understanding dimensions in millimeters for precision work.
Conversion Formula
The formula to convert feet to millimeters is:
feet × 304.8 = millimeters

Unit Definitions
Foot (ft)
A foot is an imperial unit of length equal to 12 inches or exactly 0.3048 meters. It is commonly used in the United States and United Kingdom for measuring length, height, and dimensions.
1 foot = 12 inches = 0.3048 meters = 30.48 centimeters = 0.333333 yards
Millimeter (mm)
A millimeter is a metric unit of length equal to one-thousandth of a meter (1/1000 m). It is the smallest common metric unit for length measurements and is widely used in engineering, manufacturing, and precision measurements.
1 millimeter = 0.1 centimeters = 0.01 decimeters = 0.001 meters = 0.000001 kilometers = 0.0393701 inches
