For converting litres to ounces consider the following scales:

1litre = 33.814 liquid oz (US)

So 0.04litres = 0.04 x 33.814

So 0.04litres = 1.35256

There are 1.35256 liquid oz (US) in 0.04litres.

But if you want to convert 0.04litres to normal ounces (not the fluid/liquid ones) then:

1litre = 1kg

1kg = 35ounces

So that means that

1litre = 35ounces

and 0.04litres are equal to = 0.04 x 35

0.04litres are equal to = 1.4ounces.

1litre = 33.814 liquid oz (US)

So 0.04litres = 0.04 x 33.814

So 0.04litres = 1.35256

There are 1.35256 liquid oz (US) in 0.04litres.

But if you want to convert 0.04litres to normal ounces (not the fluid/liquid ones) then:
