Converter for ozone columns

Ozone columns describe the total amount of ozone in a column of air, e.g. between the ground and the top of the atmosphere. A frequent unit for the ozone column is the Dobson Unit (DU). It is assumed, that the ozone of the column in pure form is present at normal pressure (1013.15 hPa) and at 0° C (273.15 K). The thickness of this layer is than given in "milli-centimetre" (10^-5 m). For example 300 DU correspond to a layer of 3 mm thickness under the conditions given above.

Type the value of the ozone column you want to convert into the field, behind which you find the unit. Click on the corresponding button and read the results in the other fields. Use the "delete" button to delete your calculation.

Example: What value has an ozone column of 300 DU in the SI-unit kg / m² ? At first type "300" into the field in front of the "DU" button. Click on the "DU" button. Find your result in the field in front of the "kg/m2" button (6.4243·10^-3 kg·m^-2).

Remarks:
- All results have been rounded to 5 significant digits.
- 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.
