So a principal lesson of the butterfly effect is the opposite of Redford's line: It is extremely hard to calculate such things with certainty. There are many butterflies out there. A tornado in Texas could be caused by a butterfly in Brazil, Bali, or Budapest. Realistically, we can't know.
There are 0.473176473 liter in a pint. 1 Pint is equal to 0.473176473 Liter. 1 pint = 0.473176473 L. Commonly used for measuring volume for liquid substances used widely around the world, in the countries adopted the Imperial system and the SI. There are a few types of pint, and the pint used in the US and the former colonies of this country is a liquid pint which is equal to approximately 473 mL.
Then the whole world (except the US) went metric, and the standard sizes in the metric system were adopted by bottle making, water, and soda companies. Conveniently, 1 liter, is just a little bit larger than a quart. That is, a normal (standard 1/2 liter) bottle holds just over 2 cups of water. The difference between a half liter and a pint is so small that most people donât worry about it. A glass of water is considered to be 8 ounces, or one cup, though most glasses are, in practice, larger. So if you are following a recommendation to drink 8 or 12 cups of water a day, that would be 4 or 6 bottles.
