How to Convert Micrometers to Picometers
To convert micrometers to picometers, multiply the length by the following conversion ratio: 1,000,000 picometers/micrometer.
Since one micrometer is equal to 1,000,000 picometers, you can use this simple formula to convert:
The length in picometers is equal to the length in micrometers multiplied by 1,000,000.
For example, here's how to convert 5 micrometers to picometers using the formula above.
How Many Picometers Are in a Micrometer?
There are 1,000,000 picometers in a micrometer, which is why we use this value in the formula above.
Our micrometer fraction and decimal calculator can convert micrometers and picometers, and it automatically converts the results to US customary, imperial, and SI metric values.
Micrometers and picometers are both units used to measure length. Keep reading to learn more about each unit.
How to Convert Micrometers 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 0.000197 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 micrometers (µm) into fractional inches:
- Find the decimal inches result: Convert 5 µm to inches to get 0.000197 in.
- Separate the whole inches from the decimal part: Keep the whole number 0 aside, leaving the decimal remainder 0.000197.
- Multiply the decimal part by your desired fraction denominator (16, 32, or 64) and round half up: Multiply 0.000197 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 Micrometer?
A micrometer is a unit of length equal to 1/1,000,000 of a meter (0.000001 m). One millionth of a meter (10⁻⁶ m), also known as a micron. [1]
The micrometer is classified as a metric and SI-compatible unit of length. Micrometers can be abbreviated as µm; for example, 1 micrometer can be written as 1 µm.
In the metric system, "micro" is the standard SI prefix for millionths, or 10⁻⁶. This makes the micrometer (µm) a convenient decimal multiple of the meter (m).
In practice, micrometers (µm) are widely used across fine-tolerance laboratory, analytical, and micro-scale length measurements within SI metric workflows, engineering documentation, and technical data sheets.
What Is a Picometer?
A picometer is a unit of length equal to 1/1,000,000,000,000 of a meter (1e-12 m). One trillionth of a meter (10⁻¹² m), used for atomic radii. [2]
The picometer is classified as a metric and SI-compatible unit of length. Picometers can be abbreviated as pm; for example, 1 picometer can be written as 1 pm.
In the metric system, "pico" is the standard SI prefix for trillionths, or 10⁻¹². This makes the picometer (pm) a convenient decimal multiple of the meter (m).
In practice, picometers (pm) are widely used across fine-tolerance laboratory, analytical, and micro-scale length measurements within SI metric workflows, engineering documentation, and technical data sheets.
When converting length between micrometers (µm) and picometers (pm), keep full floating-point precision (1 µm = 1,000,000 pm; 1 pm = 0.000001 µm) during intermediate calculations and round only the final picometer figure to match your instrument tolerance.
