Hum a little fast question...

[GralTok]

What's the darn circunference of Earth? and the moon as I'm at this... Both in miles if possible if not look at question 2

Oh and what is the convertion rate of KM into miles

Thanks... I just can't set myself of the circonference of the world... I just don't want only 1 isle to play on...

Try some google-fu.

From memory, 1 miles ~= 1600-odd kilometers. There again, google-fu will help you find the exact conversion rate. Use the Web, Luke...

1 km = 0.6214 miles

1 mile = 1.609 km

Thought the earth circumference was ~26,000 miles, but could be wrong.

all you ask and more

Our planet weighs in at approximately 5.972 sextillion tons - that is 5,972 followed by 18 zeros!

The earth is approximately a sphere and its volume is 1,097,509,500,000,000,000,000 cubic meters. Very big! It would take you over eight million years to count to the number of cubic meters the earth is.

Earth is 12,742 kilometers (7,900 miles) in diameter. That's how far you would have to tunnel to dig to the other side of the Earth!

The circumference of the earth at the equator is 24,901.55 miles (40,075.16 kilometers).

Thanks all!

Alsih2o All you ask and more... ok than give me the other needed mesure to make the earth as it is ... (we all know the earth is not a sphere)

equator = horizontal
I don't know what = vertical


Thanks it's not really needed but I want more

 

[dave_o]

Vertical = Prime Meridian.

On Earth, the Polar circumference is exactly 21,600 nautical miles ... by definition. This is "a given" ... and NOT open to debate. (Thankfully).

Thanks my world will be:

26112miles at the "Equator"
16896miles at the "Prime Meridian"

More flat than our dear Earth but this way it fit into a 34" x 22" sheet (or 4 17" x 11" sheet)

Er. You do realize just how impressively flat this is, right? You're talking about a world with an equatorial radius of 4155 miles, but a polar radius of just 755 miles. It has a volume, and therefore a mass, about one-fifth that of the Earth, so someone standing at the equator feels gravitational force about one-fifth of Earth's, but someone at the pole feels a force about six times that of Earth's.

Might I suggest that, if you need to draw your world on a flat sheet like this, you instead use a roundish world, and draw onto, say, a Robinson or Mercator projection?
