Answer 2

I'm sorry, but I'm not familiar with the unit "M²-mn." It doesn't correspond to any standard unit of measurement that I'm aware of. It's possible that it could be a custom unit or a typo. Could you provide more context or clarify the meaning of "M²-mn"? I'll do my best to help you once I have a better understanding.
