maxweight expresses a legal weight limit for using the way to which the tag is added. If a unit is not specified, the value is assumed to be in metric tonnes (unit = t, 1000 kg).

Imperial unit conversion

As per Map Features: Units, as of September 2014 only metric units of weight (metric tonnes or kilograms) are supported for this tag. Therefore if a maxweight for a country that uses U.S. customary or Imperial measurements is desired, a conversion is required.

1 short ton (U.S. customary) = 0.90718474 metric tons
1 long ton (Imperial) = 1.0160469088 metric tons
1 pound = 0.00045359237 metric tons
1 pound = 0.453592 kilograms


Weight Tagging Remark
5 tonnes maxweight=5 Alternatively maxweight=5 t could be used.
5.5 tonnes maxweight=5.5 Please note the dot as decimal separator!

Common mistakes

Incorrect values

Often the values themselves are not specified correct. The following table contains examples of incorrect tags and their correct notation.

Incorrect Explanation Correct
maxweight=12t The space between value and unit is missing. maxweight=12 t
maxweight=12 to The unit 'to' is not the correct unit. maxweight=12 t or maxweight=12
maxweight=3 persons The unit 'persons' and everything like this is wrong. maxweight=0.3 t
maxweight=0,6 The comma is used as wrong decimal separator. maxweight=0.6
