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.
Section
A section is a unit of area used in the US Public Land Survey System, equal to 1 square mile (640 acres or approximately 2.59 km²).
Defined by the Land Ordinance of 1785 as 1/36 of a township. Sections are numbered 1-36 within each township.
Sections are the fundamental unit of US public land records in PLSS states (essentially the central and western US). Property descriptions like 'NE quarter of section 14, township 3 north, range 2 east' use this system.
Defined by the US Land Ordinance of 1785.
Square Centimeter to Section conversion formula
The relationship between square centimeters and sections:
To convert square centimeters to sections, multiply the value in square centimeters by 3.861022e-11. To reverse, multiply sections by 2.589988e+10.

Step-by-step: convert square centimeters to sections
- Write down the value in square centimeters (cm²).
- Multiply that value by the factor 3.861022e-11.
- The product is the equivalent value in sections (sec).
- To reverse, multiply the section value by 2.589988e+10.
Worked examples
Example 1 — Convert 1 cm² to sec:
1 × 3.861022e-11 = 3.861022e-11 sec
Example 2 — Convert 100 cm² to sec:
100 × 3.861022e-11 = 3.861022e-9 sec
Real-world example — Plastic-film thickness alternates
A 150-square centimeter plastic film converts cleanly to sections — useful for packaging buyers reconciling supplier datasheets across metric and US measurement systems.
150 cm² × 3.861022e-11 = 5.791532e-9 sec
Real-world example — Hair-width scale measurements
A 70-square centimeter measurement (about the diameter of a human hair) is the kind of value materials engineers regularly express in adjacent micro-scale units like sections for direct comparison across supplier datasheets.
70 cm² × 3.861022e-11 = 2.702715e-9 sec
Real-world example — Paper and film thicknesses
At the thickness of office paper (roughly 3 square centimeters), converting between sub-millimeter units is routine for packaging and printing buyers comparing quotes from metric and US suppliers.
3 cm² × 3.861022e-11 = 1.158306e-10 sec
