1.8 million kilometers ...
Are we stuck with using kilo only? Are mega and giga bad words? It's really simple for those whom don't fear the words mega and giga.
1.8 * 1,000,000 * 1000 = 1,800,000,000 meters.
Using the proper prefix ( https://en.wikipedia.org/wiki/Metric_prefix )
1.8 giga meters.
That's easier to type and say than 1.8 million kilometers, or 1.8 mega kilo. Please, use all of the prefixes, that's what they're there for!
Each prefix increases by 1000, or 10^3
1000 meters in 1 kilo-meter
1000 kilo-meters in 1 mega-meter
1000 mega-meters in 1 giga-meter.
