I just drank 354.876 ml of Pepsi. Why would I?

So what’s with the US measurement system??? Why does it have to be so complicated??? Or is it just me??? Let me show you how the conversion works

1 inch = 2.54 cm
1 foot = 12 inches = 0.3048 cm
1 yard = 3 feet = 0.9144 cm
1 mile = 5280 feet = 1.60 km
1 fluid ounce (fl) = 8 fluid dram = 29.573 ml
1 pound = 16 oz = 453.592 g
2000 pounds = 1 ton = 907.184 kg
32 F = 0 C

The US measurement system is a confusing matter and still holds itself apart from the metric system employed by most other countries. There are a few exceptions. Medical and scientific fields use the metric system, and many items for trade are now measured in the International System of Units (SI), also called the metric system. If you are someone like me who grew up learning the “international” system (I strongly believe there is a good reason why they call it that way) your life is gonna be tough.

The SI system has a simple base 10 approach 1 Km = 1000 m = 100,000 cm = 10,000,000 mm. Now, how easy is this? Now American standards: 1 mile = 1760 yards = 5280 feet = 63360 inches. As a kid, I would go mad in trying to figure out how they could be related and I still am. Even after mastering the art of multiplication over the years, I had to use my calculator to come up with these numbers.

Now a use-case scenario: I wanna buy soda. Do I choose a 12 oz or a 16 oz cup??? BTW, these are the standard sizes available. I’d rather want a 10 oz or a 20 oz cup because of the plain reason that it’s a round number. Now, if you notice there is no underlying relation between SI system and the American standards of measurement and even if there is, I am not Einstein. I just found out that this system was called the British system and even the Brits have stopped using it a century back. Why does America resist the change?? Or is it just coz they wanna be different in everything????
