Hello, using m-units, no space appears at the end of the unit. In the example ... Dichte 2,65 \Gram\Per\Cubic\Centi\Meter, 27\% Portlandzement der Dichte 3,1 \Gram\Per\Cubic\Centi\Meter und 22\% Wasser beträgt ... appears no space before the comma and even before the "und". What wrong? Thank you, Greetings Thomas Lohmann
