the sizes become distorted because of the round curves from a globe. if you use a flat map, same rules apply.
It is a balance.
All you need is a scale. you should use a scale that measures in grams.
A accurate scale in KILOGRAMS at exactly earth's gravity . kilograms are a measure of mass.POUNDS ARE NOT.
A measuring flask.

Basically one is provided with legs and you can use these to travel round the Earth, apart from the stretches of water where you have to get a boat and row.
Use a temperature gun.
Cartographers use a projection method to show the round Earth on a flat surface. Different types of map projections, such as Mercator or Robinson, are used to represent the Earth's curved surface in two dimensions while minimizing distortion of shape, area, distance, or direction.
that the earth was round and big and it contained a force called the almighty gravity. How amazing LOL :)
