Units explained
Square Centimeter
A square centimeter is a metric unit of area equal to 10⁻⁴ m² (1 cm × 1 cm). It is widely used in everyday measurement, lab work, and small-area applications.
Derived by squaring the centimeter (1/100 of a meter). The centi- prefix comes from the Latin 'centum' (hundred).
Square centimeters express the cross-sectional area of pipes and cables, the surface area of small everyday objects, biological tissue samples, and many engineering quantities. The SI unit for medical/pharmaceutical dose-per-area is often expressed in cm².
Centimeter has been part of the metric system since 1795.
Square Yoctometer
A square yoctometer is a metric unit of area equal to one square yoctometer (10⁻²⁴ m × 10⁻²⁴ m = 10⁻⁴⁸ m²). It is the smallest SI prefix-derived area unit defined and exists primarily for theoretical completeness.
Derived by squaring the yoctometer (10⁻²⁴ m), which uses the SI prefix yocto- adopted by the CGPM in 1991. The yocto- prefix originates from the Latin 'octo' (eight), referring to the 10⁸ thousand-grouping in the power-of-thousand scheme.
Square yoctometers have no current practical application. The yoctometer scale itself lies far below any physically measurable length, including the Planck length. The unit is included for SI catalogue completeness.
SI prefix yocto- adopted in 1991; square area defined by mathematical squaring.
Square Centimeter to Square Yoctometer conversion formula
The relationship between square centimeters and square yoctometers:
To convert square centimeters to square yoctometers, multiply the value in square centimeters by 1e+44. To reverse, multiply square yoctometers by 1e-44.

Step-by-step: convert square centimeters to square yoctometers
- Write down the value in square centimeters (cm²).
- Multiply that value by the factor 1e+44.
- The product is the equivalent value in square yoctometers (ym²).
- To reverse, multiply the square yoctometer value by 1e-44.
Worked examples
Example 1 — Convert 1 cm² to ym²:
1 × 1e+44 = 1e+44 ym²
Example 2 — Convert 100 cm² to ym²:
100 × 1e+44 = 1e+46 ym²
Real-world example — From microns to sub-micron features
One square centimeter equals one thousand square yoctometers — the conversion semiconductor designers do constantly when comparing mask feature dimensions to actual transistor gate lengths.
1 cm² × 1e+44 = 1e+44 ym²
Real-world example — Infrared to visible-spectrum mapping
A 10-square centimeter thermal infrared wavelength corresponds to a much larger number in square yoctometers, the unit favoured for ultraviolet and visible-light specifications.
10 cm² × 1e+44 = 1e+45 ym²
Real-world example — Mid-micron to nanometer
3 square centimeters equals 3,000 square yoctometers — useful when relating mid-infrared wavelengths (typically quoted in microns) to nanometer-scale visible-light wavelength tables.
3 cm² × 1e+44 = 3e+44 ym²
