42 nanometers (nm) is approximately 1.38 feet (ft). To convert nanometers to feet, you need to know that 1 nanometer equals 3.28084 × 10⁻⁸ feet. Multiplying 42 by this conversion factor gives the result in feet.

Converting 42 nm to feet involves multiplying the length in nanometers by the conversion factor from nanometers to feet. Since 1 nm = 3.28084 × 10⁻⁸ ft, then 42 nm = 42 × 3.28084 × 10⁻⁸ ft, which equals approximately 1.38 ft. This conversion works because it uses a precise ratio, ensuring the measurement stays accurate.

Conversion Result and Explanation

42 nm is approximately 1.38 feet. This conversion is based on the fact that one nanometer equals 3.28084 × 10⁻⁸ feet, so multiplying 42 by this number provides the length in feet.

Understanding this conversion helps when translating very small measurements into larger, more familiar units like feet, especially in scientific or engineering contexts where precision is necessary.

Conversion Formula

The formula to convert nanometers to feet is: feet = nanometers × 3.28084 × 10⁻⁸. This works because the conversion factor from nanometers to feet is precisely 3.28084 × 10⁻⁸, which is derived from the relationship between meters and feet, and the fact that 1 nanometer is 10⁻⁹ meters. For example, converting 42 nm involves multiplying 42 by 3.28084 × 10⁻⁸, resulting in approximately 1.38 feet. This step-by-step method ensures accurate measurement translation, critical in fields requiring precise length conversions.

Conversion Example

• Convert 10 nm:
  • Multiply 10 by 3.28084 × 10⁻⁸.
  • Result = 10 × 3.28084 × 10⁻⁸ = 3.28084 × 10⁻⁷ ft.
  • So, 10 nm = 0.000328 ft approximately.
• Convert 100 nm:
  • Multiply 100 by 3.28084 × 10⁻⁸.
  • Result = 100 × 3.28084 × 10⁻⁸ = 3.28084 × 10⁻⁶ ft.
  • Which is about 0.00000328 ft.
• Convert 1,000 nm:
  • Multiply 1,000 by 3.28084 × 10⁻⁸.
  • Result = 1,000 × 3.28084 × 10⁻⁸ = 3.28084 × 10⁻⁵ ft.
  • This equals approximately 0.0000328 ft.
• Convert 5,000 nm:
  • Multiply 5,000 by 3.28084 × 10⁻⁸.
  • Result = 5,000 × 3.28084 × 10⁻⁸ = 0.000164 ft.
• Convert 42 nm (original):
  • Multiply 42 by 3.28084 × 10⁻⁸.
  • Result = 42 × 3.28084 × 10⁻⁸ ≈ 1.38 ft.
