Units explained

Metric / SI

Square Centimeter

What is a 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.

Origin of the square centimeter

Derived by squaring the centimeter (1/100 of a meter). The centi- prefix comes from the Latin 'centum' (hundred).

Where it is used

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.

When and where it was developed

Centimeter has been part of the metric system since 1795.

Square Nanometer

What is a square nanometer?

A square nanometer is a metric unit of area equal to 10⁻¹⁸ m² (1 nm × 1 nm). It is the standard unit in nanotechnology and surface science for expressing the area of nanoscale structures.

Origin of the square nanometer

Derived by squaring the nanometer (10⁻⁹ m). The nano- prefix comes from the Greek 'nanos' (dwarf).

Where it is used

Square nanometers are used to express the surface area of nanoparticles, the footprint of single molecules adsorbed on surfaces, and the active area of nanoscale electronic devices.

When and where it was developed

Nanometer adopted into SI in 1960; widespread use in nanotechnology grew through the 1990s and 2000s.

Square Centimeter to Square Nanometer conversion formula

The relationship between square centimeters and square nanometers:

1 cm² = 1e+14 nm²
1 nm² = 1e-14 cm²

To convert square centimeters to square nanometers, multiply the value in square centimeters by 1e+14. To reverse, multiply square nanometers by 1e-14.

Step-by-step: convert square centimeters to square nanometers

  1. Write down the value in square centimeters (cm²).
  2. Multiply that value by the factor 1e+14.
  3. The product is the equivalent value in square nanometers (nm²).
  4. To reverse, multiply the square nanometer value by 1e-14.

Worked examples

Example 1 — Convert 1 cm² to nm²:
1 × 1e+14 = 1e+14 nm²

Example 2 — Convert 100 cm² to nm²:
100 × 1e+14 = 1e+16 nm²

Real-world example — From microns to sub-micron features

One square centimeter equals one thousand square nanometers — the conversion semiconductor designers do constantly when comparing mask feature dimensions to actual transistor gate lengths.

1 cm² × 1e+14 = 1e+14 nm²

Real-world example — Infrared to visible-spectrum mapping

A 10-square centimeter thermal infrared wavelength corresponds to a much larger number in square nanometers, the unit favoured for ultraviolet and visible-light specifications.

10 cm² × 1e+14 = 1e+15 nm²

Real-world example — Mid-micron to nanometer

3 square centimeters equals 3,000 square nanometers — useful when relating mid-infrared wavelengths (typically quoted in microns) to nanometer-scale visible-light wavelength tables.

3 cm² × 1e+14 = 3e+14 nm²
