## Square Kilometers

One square kilometer is equal to the area of a square with sides that are 1 kilometer in length.

The square kilometer, or square kilometre, is a multiple of the square meter, which is the SI derived unit for area. In the metric system, "kilo" is the prefix for 10^{3}. A square kilometer is sometimes also referred to as a square km. Square kilometers can be abbreviated as *sq km*, and are also sometimes abbreviated as *km²*. For example, 1 square kilometer can be written as 1 sq km or 1 km².

## Acres

One acre is defined as the area equal to a space that is one chain (66 ft) by one furlong (660 ft), or 10 square chains. That's equal to 43,560 square feet for those unfamiliar with those units of measure.

The acre is a US customary and imperial unit of area. Acres can be abbreviated as *ac*, for example 1 acre can be written as 1 ac.

## Unit of Measurement Conversion Made Easy!

There are thousands of units of measure in use across the globe, and converting from one to another can be very difficult since each conversion requires a different formula to derive the result. Our unit of measurement conversion tools are meant to be dead easy. We break the mold of the typical dry and complicated experience. In addition to converting from one measurement to another, we provide the formula so you can see how the conversion is done, use it on you’re own calculator if you need to!

## Understanding the Metric System

The metric system makes it relatively easy to convert from one metric unit to another metric unit. The metric system uses a base unit, think meters or grams, and a prefix such as kilo or milli. The prefixes differ from the base units by differing powers of 10. So to convert within the metric system it’s usually a matter of multiplying or dividing by one of the powers of 10.

### Here is a list of some of the common metric prefixes:

- “kilo” – 1,000x larger
- “hecto” – 100x larger
- “deca” – 10x larger
- “deci” – 10x smaller
- “centi” – 100x smaller
- “milli” – 1,000x smaller

There is a helpful mnemonic for remembering the prefixes: “King Henry Died Until Drinking Chocolate Milk.”

The u in Until refers to the base unit.
