941 milliliters is the same as: cm3 and L
Nutka1998 [239]

For this case, we must take into account the following conversion factors:

1 mL = 1 cm ^ 3

1000 mL = 1 L

Therefore, by applying the conversion factors we have:

For cubic centimeters:

(941mL) (1\frac{cm^3}{mL}) = 941cm ^ 3

For liters:

(941mL) (\frac{1}{1000}\frac{L}{mL}) = 0.941L

Answer:

941 milliliters is the same as:

941cm ^ 3

0.941L
