How to Convert Feet to Nanometers
To convert feet to nanometers, multiply the length by the following conversion ratio: 304,800,000 nanometers/foot.
Since one foot is equal to 304,800,000 nanometers, you can use this simple formula to convert:
The length in nanometers is equal to the length in feet multiplied by 304,800,000.
For example, here's how to convert 5 feet to nanometers using the formula above.
How Many Nanometers Are in a Foot?
There are 304,800,000 nanometers in a foot, which is why we use this value in the formula above.
Our foot fraction and decimal calculator can convert feet and nanometers, and it automatically converts the results to US customary, imperial, and SI metric values.
Feet and nanometers are both units used to measure length. Keep reading to learn more about each unit.
How to Convert Feet to Fractional Inches (1/16″, 1/32″ & 1/64″)
Plain-language method for turning decimal inches into a standard tape-measure or machinist ruler fraction
Calculators give you a decimal number (such as 60 in), but tape measures and woodworking rulers are marked in binary fractions of an inch—most commonly 1/16″ on carpenter tapes, 1/32″ on fine woodworking rules, and 1/64″ on machinist scales.
Here is the step-by-step worked example for converting 5 feet (ft) into fractional inches:
- Find the decimal inches result: Convert 5 ft to inches to get 60 in.
- Separate the whole inches from the decimal part: Keep the whole number 60 aside, leaving the decimal remainder 0.
- Multiply the decimal part by your desired fraction denominator (16, 32, or 64) and round half up: Multiply 0 by 16, 32, or 64, then round to the nearest whole number (values ending in .5 round up).
- Reduce the fraction to lowest terms: If the rounded top number (numerator) is even, divide both top and bottom by 2 (or their Greatest Common Divisor) until the top number is odd, then combine with your whole inches.
What Is a Foot?
A foot is a US customary and imperial unit of length equal to 12 inches or 1/3 of a yard. Under the 1959 International Yard and Pound Agreement, one foot is legally defined as exactly 0.3048 meters (30.48 centimeters). [1]
Feet are widely used in the United States, Canada, and the United Kingdom for human height, building construction, real estate floor plans, and aviation altitude. Feet can be abbreviated as ft; for example, 1 foot can be written as 1 ft.
Feet can also be denoted using the ′ symbol, known as a prime (or a single quote ' for convenience). For example, 5 feet 10 inches is frequently written as 5′ 10″ or 5' 10".
Feet are measured using 12-inch rulers, carpenter's folding rules, 25-foot steel tape measures, and laser distance meters across residential framing, architecture, and surveying.
What Is a Nanometer?
One nanometer is equal to one-billionth (1/1,000,000,000) of a meter, which is defined as the distance light travels in a vacuum in a 1/299,792,458 second time interval. [2]
The nanometer, or nanometre, is a multiple of the meter, the SI base unit for length. In the metric system, "nano" is the prefix for billionths, or 10⁻⁹. Nanometers can be abbreviated as nm; for example, 1 nanometer can be written as 1 nm.
Because 1 inch equals 25.4 millimeters and 1 millimeter equals 1,000,000 nanometers, there are exactly 25,400,000 nanometers in 1 inch (and 10 Angstroms in 1 nanometer).
The nanometer is an extremely small unit of length measurement, often used to measure things that are very small, such as the wavelengths of visible light (400 nm to 700 nm), the transistors and electrical pathways in computer processors, and thin-film nanotechnology.
When converting length between feet (ft) and nanometers (nm), keep full floating-point precision (1' = 304,800,000 nm; 1 nm = 3.28084e-9 ft) during intermediate calculations and round only the final nanometer figure to match your instrument tolerance.
