You just have to memorize this stuff, at least the ones you work with all the time. It's ok to bookmark the page so you can look up the others when you run across them.
There is a prefix every three powers of ten, except for 100, 10, 1/10, and 1/100. To go from one to another you use the LARD rule: LEFT ADD RIGHT DEDUCT. When moving the decimal to the LEFT you ADD to the power of ten. When going to the RIGHT you DEDUCT from the power of ten.
No less “prime” is earth’s “street,” or orbit within our solar system “city.” About 93 million miles from the sun, this orbit is in what scientists call the circumstellar habitable zone, where life neither freezes nor fries. Moreover, earth’s path is almost circular, keeping us roughly the same distance from the sun year-round.
Another vital detail is our earth’s path around the sun. Comets have a wide elliptic path. Thankfully, this is not so with the earth. Its orbit is almost circular. Again, this prevents us from experiencing death-dealing extremes of temperature.
“When I see your heavens, the works of your fingers, the moon and the stars that you have prepared, what is mortal man?” (Psalm 8:3, 4). Let us give the glory to the Creator Jehovah not evolution.
