A square centimeter (cm2) is a fundamental unit of area in the metric system.
It represents one ten-thousandth of a square meter (10-4 m2).
The plural form is square centimeters.
A square centimeter is the area of a square with sides that are each one centimeter long.
To visualize this, picture the surface area of a single sugar cube or the nail on your pinky finger.
This small, tangible size makes it a go-to unit for measuring smaller objects in science, design, and everyday life, such as the area of a postage stamp or a small electronic component.
The square centimeter is directly derived from the meter.
Since there are 100 centimeters in a meter, a square meter (1m x 1m) contains 10,000 square centimeters (100cm x 100cm).
This relationship is expressed as:
1 m2 = 10,000 cm2
This simple, base-10 conversion is a key advantage of the metric system, making calculations straightforward and precise.
Knowing how to convert square centimeters is crucial. Here are the most common conversions you'll encounter:
To Square Millimeters (mm2): Since 1 cm equals 10 mm, one square centimeter is 10 mm × 10 mm.
1 cm2 = 100 mm2
To Square Inches (in2): The conversion is approximate, as it bridges the metric and imperial systems.
1 cm2 ≈ 0.155 in2
This conversion is crucial in fields that operate with both metric and imperial systems, such as international trade and manufacturing.
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:
