Find: Feet to Kilometers Converter

Kilometers to Feet Formula

The exact conversion factor is:

$$
1 \text{ kilometer} = 3,280.84 \text{ feet}
$$

Conversion Formula:

$$
\text{Feet} = \text{Kilometers} \times 3,280.84
$$

Quick rule: Multiply kilometers by 3,280.84.

Why 3,280.84?

Because:

  • 1 kilometer = 1000 meters
  • 1 meter = 3.28084 feet

So:

$$
1000 \times 3.28084 = 3,280.84
$$

Step-by-Step Examples

Example 1: Convert 1 km to feet

$$
1 \times 3,280.84 = 3,280.84 \text{ ft}
$$

Answer: 1 km = 3,280.84 ft

Example 2: Convert 5 km to feet

$$
5 \times 3,280.84 = 16,404.2 \text{ ft}
$$

Answer: 5 km = 16,404.2 ft

Example 3: Convert 0.5 km to feet

$$
0.5 \times 3,280.84 = 1,640.42 \text{ ft}
$$

Answer: 0.5 km = 1,640.42 ft

Quick Conversion Table

Kilometers (km) Feet (ft)
0.1 km 328.084 ft
0.5 km 1,640.42 ft
1 km 3,280.84 ft
2 km 6,561.68 ft
5 km 16,404.2 ft
10 km 32,808.4 ft

Reverse Conversion (Feet to Kilometers)

To convert feet back to kilometers:

$$
\text{Kilometers} = \text{Feet} \times 0.0003048
$$

or

$$
\text{Kilometers} = \text{Feet} \div 3,280.84
$$

How the km to ft Calculator Works
