# How big is a million grains of sand?

A medium-sized grown-up woman has about 18 square feet, and a man has more than 20 sq ft. Each grain is 1/1,000th of a foot wide, so it takes 1,000 x 1,000 or about 1 million grains of sand to cover just 1 square foot.

Arcturus is 25 times larger than our sun. Arcturus emits more than 100 times the light of our sun in visible light. Arcturus is 200 times more powerful than the sun.

On September 22 or 23, the sun moves out of the sign of Virgo and into the sign of Libra. If you were born around those dates, it's possible that you have a connection to the traits of the cusp sign.

### You can also ask why are some beaches sand and some pebbles?

Higher-energy beaches are often characterised by larger particles, such as pebbles or even boulders. The chalk is dissolved in the sea water, leaving the flint behind, and this combined with the steeply sloping shoreline gives us the pebbly beaches. Is beach sand and desert sand the same? The biggest and most important difference is beach sand is full of salt and desert sand is not. When ocean water wets beach sand the water evaporates but leaves the salt behind. Other than that it depends on what the sand was BEFORE it actually weathered into sand. That would be the only other difference.

### How many grains of sand are in galaxies?

The number they calculated was seven quintillion five quadrillion (that's 7.5 followed by seventeen zeros or 7.5 billion billion) sand grains! Correspondingly, how much sand is in a beach? Earth's beaches contain roughly 5,000 billion billion-aka, 5 sextillion-grains of sand. We've now estimated that there are about 8,000,000,000 equal to 8x10^9 grains of sand per cubic meter of beach, and that the Earth contains roughly 700,000,000,000 equal to 7x10^11 cubic meters of beach.
