Suuruusluokista, also known as orders of magnitude, refers to the ratio between two quantities of the same kind. It is a measure of the relative size of one quantity compared to another. In scientific and mathematical contexts, orders of magnitude are used to describe the scale of phenomena, such as the size of objects, the magnitude of forces, or the duration of events. For example, the distance from Earth to the Moon is approximately one order of magnitude larger than the diameter of Earth.

Orders of magnitude are typically expressed as powers of ten. For instance, a quantity that is two orders of magnitude larger than another is 100 times greater. Conversely, a quantity that is three orders of magnitude smaller is 1,000 times smaller. This concept is fundamental in various fields, including physics, engineering, and biology, where it helps to understand and compare the scales of different phenomena.

In everyday language, the term "order of magnitude" is often used to indicate an approximate or rough estimate. For example, one might say that a particular event is on the order of magnitude of a million dollars, meaning it is roughly in that range, but not necessarily exactly that amount. This usage reflects the idea that the exact value is not as important as the general scale or size of the quantity.
