For one, the NASA article says 5 million miles (12 solar radii), not kilometers. So it's actually about 2/3 the quoted number.

- kwhitefoot 5y agoDoesn't NASA have some sort of educational duty? Surely they should be using SI units always so as to avoid exactly this kind of confusion.
- nine_k 5y agoI'd rather have them always use both units, so that people would eventually learn intuitively, by example, what a km is relayed to a mile, or a kg to a pound, etc.
- kwhitefoot 5y agoYes, but the primary units should always be SI. They can put the US Customary units in brackets after.
