There is a science to approximating but that is another thread for another day.
You wouldn't be an engineer by chance? I attended an engineering college when your personal calculator was made of bamboo, was 10" long, and had 3 1/2 digit accuracy. One of my math classes included "estimating" (approximating) and significant figures.
My quibble wasn't with the "rounding" but the magnitude was off by three orders of magnitude on the land area of Texas. They have ranches bigger than 270 square miles. The actual population density was "close enough for government work."

LOL!!! I meant 270,000 sq miles. I thought I used the “K” to make it in thousands.
Hey, my rounding was only off by A THOUSAND (that’s my story and I’m sticking to it).
Thanks for checking my figures. I have messed up before when doing a similar calculation — that is why I showed my work.
FWIIW: France is about 210,000 square miles (smaller than Texas). We could put all the population of France in the DFW Metroplex (14,500 square miles). But WHY? The last thing we need here is a bunch of lazy, smelly frogs.
