When it comes to money, things get complicated. For most units of measurement, things are static. For example a kilogram will always be 1000 grams. And conversion will also be strait forward. 1 kilogram will be about 2.2 lbs. But what if one day, a kilogram went up in weight to 1067 grams? Or if converting 3000lbs became about 1 light year?
This seems to be the way with money. Why cant a system be setup so that a pound sterling has a specific value, for example £1 will always get you a loaf of bread, or 3 millilitres of unleaded. Why does stuff have to go up?
Conversion is even more baffling. At least for someone who knows the complete F.A on economics. £1 used to be worth 2 U.S bucks some time back. No idea what it's actually worth now but apparently it's more like 1.5 U.S bucks. What are the reasons for this, and why are there not international standards setup for currency conversion and the value of each unit?
This probably sounds ridiculous but it's how my mind works. This is just one thing I often wonder about.
