Factors are entered by hand from NIST Handbook 130 rather than derived from a units library, so the ones that terminate are exact rather than rounded.
The same converter answers this pair however it is written: litres to US fluid ounces is the British spelling of the same units — the metre and the litre are spelled that way outside the United States and the quantity does not change.

A fluid ounce is a volume, and there are two of them
The US fluid ounce is exactly 29.5735295625 ml; the imperial fluid ounce is exactly 28.4130625 ml. This page uses the US one. And a fluid ounce is not an ounce of weight: eight fluid ounces of honey weigh about twelve ounces, which is the reason baking by weight travels and baking by cup does not.
NIST Handbook 44, Appendix C — general tables of units of measurement
What is a liter?
One cubic decimeter. A liter of water weighs almost exactly one kilogram, which is how the unit was designed.
What is a US fluid ounce?
Exactly one 128th of a US gallon, which makes it 29.5735295625 ml exactly. The imperial fluid ounce is a different unit at exactly 28.4130625 ml, so a UK recipe calling for 10 fl oz means 284 ml and a US one means 296 ml. It is also a volume, not a weight: an ounce of flour is not a fluid ounce of flour.
How many US fluid ounces are in a liter?
One liter is 33.814023 US fluid ounces. Going the other way, one US fluid ounce is 0.02957353 liters. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
