# ft to mm The method to convert feet to miles is very simple. To convert a feet measurement to a millimeter measurement, multiply the length by the conversion ratio.

## What do you mean by Feet?

A Feet is measuring unit of length in the imperial system and US customary systems. The symbol of the feet is “ft”. One foot is equal to 304.8 mm.

Using the prime symbol, which helps you in the conversion of feet 1 ft can be written as 1′.

## What do you mean by Millimeters?

A millimeter (symbol: mm) is a unit of length in the International System of Units (SI).

The millimeter is a unit of length in the metric system, equivalent to one thousandth of a meter (the SI base unit of length). Metric unit of length equal to one thousandth of a meter, which is the SI base unit of length.

Conversion of Centimeter to Millimeters

## How do You Calculate Feet to Millimeters?

To convert a feet measurement to a millimeter measurement, multiply the length by the conversion ratio. One feet is equal to 304.8 millimeters, you can use this simple formula to convert:

1 foot is equal to 304.8 millimeters:
1 ft = 304.8 mm
The distance d in millimeters (mm) is equal to the distance d in feet (ft) times 304.8:
d(mm) = d(ft) × 304.8

Example:

• Convert 2 feet to millimeters:
d(mm) = 2ft × 304.8 = 609.6mm.
• Convert 18 feet to mm
1 ft = 304.8 mm
So, 18 ft = 18 x 304.8 = 5486.4 mm

## Present Uses of Feet:

The foot is primarily used in the United States, Canada, and the United Kingdom for many everyday applications. In the US, feet and inches are commonly used to measure height, shorter distances, field length (sometimes in the form of yards), etc. Feet are also commonly used to measure altitude (aviation) as well as elevation (such as that of a mountain).

## Present Uses of Millimeters:

Millimeters are used to measure very small but visible-scale distances and lengths. In terms of real-world comparisons, a millimeter is roughly the size of the wire used in a standard paper clip. The metric system is based on decimals: There are 10mm in a centimeter and 1000mm in a meter.
