Field Calculator

Several calculators for shape, size and perimeter of a field and for different units of measurement. Here, with field a piece of land or something similar is meant. Often fields are rectangular, but there are of course many other forms. Some of these forms, which can be placed side by side in a way that no gaps remain, can be calculated on the following pages. These forms are called tessellable. Also often occuring shapes that cannot be tesselated can be calculated here.

Units of Measurement

Conversion of different scale units for an area. The size of an area is measured in square units. For pieces of land, a common unit in Europe is the are, which is 100 square meters. Derived from that is the hectare, which is 100 are or 10000 m².
Please enter one value, this will be converted into all the other values.

Each of these calculators allows you to select different units of measurement for each input field, with frequently used and compatible units preselected. These are meters, hectares and, if necessary, degrees. Hectare is the usual unit of area for land; one hectare corresponds to one hundred meters by one hundred meters, or ten thousand square meters. Even larger plots of land are given in square kilometers, with one km² corresponding to one thousand meters by one thousand meters, or one million square meters.
Round fields, semi-circular fields and those in the shape of a section of a circle are relevant for artificial irrigation when the irrigation system rotates around the center of the field. Such areas are calculated using the number pi, π, which is why whole values are never reached here.

Other calculators on this page that are relevant to the topic are for calculating the average area per person and for the volume on an area.
