How do you divide oil?

My friend just got some oil from California in 5 gram containers, and wants to divide it into single grams. What would be the best way to do this? Thanks

Put it in the fridge til able to break up and weigh

what kind of container are they in? glass?

if its in a glass container, you can just heat up container with a lighter, slowly and evenly, and it will liquify the oil and will easily pour out into smaller glass containers.
