Yes ace is correct. If I write tonnes then I mean tonnes noting else. I have and will always use the correct standard and that is the metric. I'm not stupid ..... Or are I!
erik_t if I draw Wärtsilä generators, a Scandinavian company. In Scandinavia we have always used the correct system and that is the metric system. every thing else is sooooo old-fashioned!!! hahaha
You clearly don't know anything of Scandinavian measurement standards.
Oh yeeaaaah!
I have always used metric, but I know some is using imperial. and Norway had they version of imperial/metric units, Denmark and Sweden to. I did see that often before when I was building traditional boats, we had to use Danish inches instead of Norwegians, but when we made a copy of a British lifeboat we used the British units from 1600/1700, So yeah I know about them. but I have never bean comfortable with these units.
