Don’t blame them. It’s really complicated for them, you need to multiply or divide by 10th to convert. That’s Math! Don’t try to explain that to someone who uses his Feet to measure things. At least NASA uses the metric system (because they know is better), but don’t tell that to US Americans.

Ehhh…. They are already overwhelmed in German, how do you imagine it working in English? I went to the immigration office in my city once, they barely spoke English, it’s really sad. If they genuinely want to attract scientists/experts, they need to establish a dedicated office for that purpose, or perhaps an office at the EU level. How does this process work in the Netherlands?
