This converter allows to transform measured lengths on maps and scaled drawings to lengths in reality. Conversions vice versa are also possible.

Usage: When the scale of your map or drawing is known, just enter it into the darker field on top. For example type "50000" into the field for a scale of 1:50000. Afterwards you may type lengths on the map or in reality in different units into the corresponding lighter field. Click on any empty space of the window or on the "calculate" button, and the other values will be calculated.

When you do not know the scale, at first activate the checkbox "calibration". Next type a length on the map in centimetre or in inch into the suitable field and, finally, type the corresponding length in reality into the field with the correct unit. After a click on any empty space of the window or on the "calculate" button the scale is calculated and you may start to convert distances.

Use the "delete" button to delete entries and the "reset" button to reset. Move the mouse over a unit or click on it to read its full name.

Examples: By which length a distance of 23 km is displayed on a map with a scale of 1:50000 ? At first, type "50000" into the darker field on top and, afterwards, type "23" into the km-field in the right column. After a click on any empty space of the window or on the "calculate" button, you may read the result in the left column (46 cm or 18.11 in).

On a scaled drawing of an appartment 10 cm correspond to 4 m in reality. How are 1.2 m displayed on this map ? At first activate the checkbox "calibration". Next type "10" into the cm-field in the left column and afterwards "4" into the m-field in the right column. After a click on any empty space of the window or on the "calculate" button the scale is calculated (1:40) and you may start conversions. Type "1.2" into the m-field in the right column and read the result in the left column after another mouseclick on any empty space of the window or on the "calculate" button (3 cm).

The calibration may also be used to enter older scales like 1 inch : 1 mile (1:63360).

Remarks:
- Large and small numbers are written exponentially. As example 2.3e5 = 2.3⋅105 = 230000 or 4.5e-5 = 4.5⋅10-5 = 0.000045.
- There is no warranty for the conversion. Cactus2000 is not responsible for damage of any kind caused by wrong results.
- Please send an email if you have suggestions or if you would like to see more conversions to be included.

- A collection of all Cactus2000-converters running offline may be ordered for a price of € 15.-. A test version is available for download for free.
