If you're being pedantic about science-related matters, it's 1290 km/h. Don't give false precision with your conversion; there's no way the original measurement

  You’re right I did just paste that figure from Google conversions. Using the metric system over the imperial system isn’t being pedantic, it’s just courtesy in 2019

    It's from a USA-based newspaper. I hate imperial with a passion, but it is still their backarsed standard. Surely anyone with a scientific bent can do a rough calculation in their head. For me, it was "oh, around 1300 km/h, cool" and moved on...

      In many countries, miles are as obscure to people as leagues, perches and gills probably are to you. In others, the word refers to a significantly different measure. For example, Norwegian and Swedish people often use the word to mean 10km, and can misunderstand a phrase like "it's just five miles outside London".
