An are (a) is a metric unit of area, defined as 100 square meters (100 m2).
It is part of the same system as the more widely known hectare. The plural form is ares.
The hectare (ha), a much more common unit for measuring land, is derived directly from the are.
The prefix 'hecto-' means 100, so one hectare is equal to 100 ares.
Since one are is 100 square meters, a hectare is equivalent to 10,000 square meters (100 ares × 100 m2/are). This makes the hectare an ideal unit for measuring large areas, such as farms, forests, and parks.
The are was first established as part of the original French metric system in 1795. It was designed to serve as a standard base unit for measuring land, simplifying calculations required by older, traditional units.
While the hectare is more common today in agriculture and forestry, the are is still used in specific contexts, such as real estate and land registries in many countries, particularly throughout Europe.
The are serves as the foundation for other metric units of land area, making conversions straightforward. The most common related units include:
Ever wonder how companies fit billions of circuits onto a computer chip the size of your fingernail? The magic happens at a scale almost too small to imagine, measured in units called square nanometers.
A square nanometer (nm2) is a unit of area in the metric system, equal to one-quintillionth of a square meter (10-18 m2).
It represents the tiny spaces where the building blocks of our world and our technology are designed and manufactured.
It can be difficult to visualize just how small a square nanometer truly is. This is the scale where we measure individual atoms and molecules.
To put its size into perspective, a single strand of human DNA has a cross-sectional area of approximately 2 to 3 square nanometers. For another comparison, a single sheet of paper is about 100,000 nanometers thick. A square nanometer is an incredibly tiny patch on a surface that is unimaginably smaller.
This minuscule scale is why the nm2 is a fundamental unit in nanotechnology, materials science, and molecular biology. Scientists use it to measure everything from the surface area of nanoparticles to the layout of transistors on a computer chip.
The nm2 is crucial in the semiconductor industry.
The "process node" of a computer chip (e.g., 5 nm or 3 nm)—a key measure of how small and advanced its components are—directly relates to the density of its transistors.
These transistors, the tiny on/off switches that power all modern electronics, are measured in terms of their area in square nanometers. A smaller transistor footprint allows manufacturers to pack billions more of them onto a single chip. Moore's Law famously describes this trend.
This increased density directly leads to more powerful, faster, and more energy-efficient electronic devices, from smartphones to supercomputers.
Understanding how the square nanometer relates to other metric units is key to working in many scientific fields.
Accurately scaling measurements from the macroscopic world down to the nanoscale is essential for design and analysis.
A square nanometer is equivalent to 10-18 square meters (m2). Here are some other common conversions:
