42 nanometers (nm) is approximately 1.38 x 10-7 feet (ft).
Since 1 nm equals 3.28084 x 10-8 feet, multiplying 42 nm by this conversion factor gives the length in feet, resulting in about 1.38 x 10-7 ft. This small length shows nanometers are much smaller than feet, so the conversion involves a tiny number times a large unit.

Conversion Formula
The formula to convert nanometers (nm) to feet (ft) is: ft = nm × 3.28084 × 10-8. This works because 1 nm equals 3.28084 × 10-8 feet. To perform the conversion, multiply the number of nanometers by this factor. For example, 42 nm: 42 × 3.28084 × 10-8 = 1.3775 × 10-6 ft.
Conversion Example
- Convert 10 nm to ft:
- Multiply 10 by 3.28084 × 10-8
- 10 × 3.28084 × 10-8 = 3.28084 × 10-7 ft
- Convert 100 nm to ft:
- 100 × 3.28084 × 10-8 = 3.28084 × 10-6 ft
- Convert 250 nm to ft:
- 250 × 3.28084 × 10-8 = 8.2021 × 10-6 ft
- Convert 500 nm to ft:
- 500 × 3.28084 × 10-8 = 1.64042 × 10-5 ft
- Convert 1000 nm to ft:
- 1000 × 3.28084 × 10-8 = 3.28084 × 10-5 ft

Conversion Definitions
“nm” stands for nanometer, which is one-billionth of a meter (1 nm = 10-9 meters), used to measure extremely tiny distances like atoms or molecules in scientific contexts.
“ft” is the abbreviation for foot, a unit of length equal to 12 inches or approximately 0.3048 meters, primarily used in the United States and some other countries for measuring height, length, or distance.
Conversion FAQs
How precise is the conversion from nanometers to feet?
The conversion is highly precise when using the exact factor of 3.28084 × 10-8. Small variations in the conversion factor can slightly affect the result, but for most practical purposes, the precision is sufficient.
Why is the value of nanometer so much smaller than the foot?
Nanometers are used to measure objects at atomic or molecular scales which are incredibly tiny. Feet measure much larger distances. Because of this, converting from nm to ft results in very small numbers, showing the vast scale difference.
Can I use this conversion for other length units?
This specific conversion factor applies only between nanometers and feet. For other units, different factors are needed, such as inches, meters, or miles. Always check the appropriate conversion rate for your units.
What happens if I input a negative number?
Entering a negative number will give a negative length in feet, which isn’t physically meaningful for measurement but mathematically valid. It’s best to input only positive numbers when measuring lengths.
Is there a quick way to estimate nanometers in feet without calculation?
For rough estimates, remember that 1 foot equals about 3.048 × 108 nanometers. So, dividing nm by this number gives an approximate length in feet. Still, for precise measurements, use the exact conversion factor.
