An acre (ac) is a common unit of area used to measure land in the United States and the United Kingdom.
It is equal to exactly 43,560 square feet.
Because it can be hard to picture that size, this guide breaks down the acre's origins, dimensions, and how it compares to other units.
The acre has deep roots in agriculture. Historically, it was defined as the amount of land that one person with a single ox could plow in one day.
This practical, work-based unit was measured as an area one "furlong" long (660 feet) by one "chain" wide (66 feet).
This origin explains why the acre became a standard for land measurement long before modern units were adopted.
Many people ask about the dimensions of an acre, but because it's a measure of area, it has no required shape or specific length.
While it equals 43,560 square feet, it doesn't have to be a perfect square. An acre can be a long rectangle, an L-shape, or even a circle—as long as the total area adds up.
To help you visualize an acre, imagine a standard American football field, including the end zones. One football field is about 1.32 acres, which means a single acre would cover about three-quarters of it.
While the acre is standard in the US, most of the world uses the hectare, a metric unit of land measurement.
This difference is crucial for anyone working in international real estate, agriculture, or science.
Here's a simple acre to hectare conversion:
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:
