Hello !

Is there any differences between the units "gr" and "g" when modeling the inputs on OpenLCA ?

Instinctively, for me, both refers to the unit "grams". However, when I model for the same process and same inputs, just by changing the units, I obtain two different results for the impact categories.

Thank you !

You can check all units in "Background data / Unit groups / Technical unit groups". Of course you can also remove or add your own units if you wish. In the pre-defined units, the abbreviation "gr" stands for "grain" and corresponds to 0.06479891 grams (see https://en.wikipedia.org/wiki/Grain_(unit)).
