milliliters (mL) and liters (L) are units used to measure volumes
1 L is made of 1000 mL
this means that 1000 mL make up 1 L
then 1 mL is equal to - 1/1000 L
therefore 1939 mL equals - 1 / 1000 mL/L x 1939 mL = 1.939 L
we have to round this off to the nearest tenth, digit in the tenths place is 9.
digit in the hundredth place is 3, since its less than 5 we dont change the digit in the tenths place.
therefore amount of liters rounded to the nearest tenth is - 1.9 L
