The bacterium Bordetella pertussis is the primary whooping cough cause. There are no other causes, and the infection follows no distinct seasonal pattern. People may become infected with the bacteria by breathing in tiny droplets released into the air by an infected person's cough or sneeze.
There are approximately 1,892.7 milliliters in 1 half-gallon of volume. That works out to 3,785.4 milliliters per gallon, 1.892 liters per half-gallon and 3.785 liters per gallon.
The answer to the question how many gallons are in 50 liters depends on the measure you have. The US liquid gal is 3.785411784 L, the imperial gal is equivalent to 4.54609 L, and the US dry gallon is approximately 4.405 L. When we write 50 liters to US gallons we mean US liquid gallons unless stated differently.
