User Guide

This tool will calculate the area of a rectangle from the dimensions of length and width.  No manual conversion is necessary for length, width and area units, which can all be selected independently. The calculator will take care of the conversion of values entered in different units.

Once the measurements for length and width have been entered, and the units for each along with the required area units, the calculated area value will be shown in the answer box highlighted in red. Also a graphic of the Area shape and dimensions will be drawn which will refresh each time the entered inputs are changed.

Formula

The formula used by this calculator to calculate the area of a rectangular shape is:

A = L · W

Symbols

  • A= Area
  • L = Length
  • W = Width

Area Dimensions – Length & Width

Enter the measurements for length and width for the rectangular shape you are calculating, and select the appropriate units for each measurement value entered.

The following conversion factors in metres (m) are used for converting length and width into different units:

  • nanometre (nm) – 0.000000001 m
  • micrometre (µm) – 0.000001 m
  • thousandth of an inch (thou) – 0.0000254 m
  • millimetre (mm) – 0.001 m
  • centimetre (cm) – 0.01 m
  • inch (in) – 0.0254 m
  • foot (ft) – 0.3048 m
  • yard (yd) – 0.9144 m
  • metre (m) – 1 m
  • kilometre (km) – 1,000 m
  • mile (mi) – 1,609.344 m
  • nautical mile (nmi) – 1,852 m

Area Calculation

This is the calculated area of the rectangle, which this tool determines by multiplying together the length and width measurements. Select the required area measurement units to display the result.

The following conversion factors in square metres (m²) are used to convert the calculated area into different units:

  • square nanometre (sq nm) – 1 x 10-18 m²
  • square micrometre (sq µm) – 1 x 10-12 m²
  • square thousandth of an inch (sq thou) – 6.4516 x 10-10 m²
  • square millimetre (sq mm) – 0.000001 m²
  • square centimetre (sq cm) – 0.0001 m²
  • square inch (sq in) – 0.00064516 m²
  • square foot (sq ft) – 0.09290304 m²
  • square yard (sq yd) – 0.83612736 m²
  • square metre (sq m) – 1 m²
  • acre (ac) – 4046.8564224 m²
  • hectare (ha) – 10000 m²
  • square kilometre (sq km) – 1,000,000 m²
  • square mile (sq mi) – 2589988.110336 m²
  • square nautical mile (sq nmi) – 3429904 m²
