Units explained
Centimeter
A centimeter is a metric unit of length equal to one hundredth of a meter (1/100 m). It is one of the most commonly used SI sub-units in daily life, especially for measuring small objects, body dimensions, paper sizes, and short distances.
The centimeter emerged from the French metric system established by the French Academy of Sciences in 1793. The metric system introduced decimal-based prefixes (milli-, centi-, deci-, deca-, hecto-, kilo-) to create proportional sub-units of the meter.
Centimeters are the standard unit for everyday measurement in nearly every country outside the United States. They are used for body height, clothing sizes, rainfall, paper formats (A4 is 21 × 29.7 cm), screen dimensions, and most consumer product specifications.
Developed in France during the late 18th century as part of the metric system designed by the French Academy of Sciences. Formally adopted in France in 1795 and ratified internationally through the Metre Convention signed in Paris in 1875.
Fermi
A fermi is a unit of length equal to one femtometer (1×10⁻¹⁵ m). It is named after physicist Enrico Fermi and is widely used in nuclear physics as a synonym for the femtometer.
The fermi was introduced informally in mid-20th-century nuclear physics literature. Although the BIPM has formally standardised the SI name 'femtometer', the fermi remains in widespread informal use.
Fermis are used to express nuclear sizes, hadron radii, and characteristic length scales in particle physics. Functionally identical to the femtometer.
Named after Enrico Fermi; in informal use from the 1950s; officially equivalent to the SI femtometer.
Centimeter to Fermi conversion formula
The relationship between centimeters and fermis:
To convert centimeters to fermis, multiply the value in centimeters by 1e+13. To reverse, multiply fermis by 1e-13.
How to use this converter

Step-by-step: convert centimeters to fermis
- Write down the value in centimeters (cm).
- Multiply that value by the factor 1e+13.
- The product is the equivalent value in fermis (F).
- To reverse, multiply the fermi value by 1e-13.
Worked examples
Example 1 — Convert 1 cm to F:
1 × 1e+13 = 1e+13 F
Example 2 — Convert 100 cm to F:
100 × 1e+13 = 1e+15 F
Real-world example — Centimeter to wavelength scale
One centimeter equals 10 million fermis. Physics curricula use this kind of conversion to relate everyday measurements to atomic and optical scales.
1 cm × 1e+13 = 1e+13 F
Real-world example — Small-scale to atomic-scale
One centimeter equals 10 million fermis — useful for physics curricula that relate everyday measurements to atomic and optical scales.
1 cm × 1e+13 = 1e+13 F
