Directions

For the Circumference of the Earth at a given Latitude, the equatorial radius of 6378.137 kilometers and polar radius of 6356.752314 kilometers were used.
For "Rotational speed of a "stationary object" at the given Latitude", a sidereal day of
23 Hours 56 Minutes 4.1 Seconds - 86,164.090530833 seconds was used.

Material on a Roll Calculator results are approximations.

Surface Area is in square units.
Volume is in cubic units.
Type the number in the box and then click "Click to Calculate"
If the number is 6.7 then type "6.7" (no quotation marks).
You may type the decimal point.
If the number is 2154 you may type "2,154", you may type the comma. Type "2,154".
If you want to type "256,678", but you type "25k,678", the computer will use "25678" to
calculate the answer.
If you type "ghblxz", the computer will use "0" to calculate the answer.
If you type "1.9e2", the computer will use "190" to calculate the answer.
