Methylcobalamin

Methylcobalamin is also known as mecobalamin. It is a form of vitamin B12 thatyour body does not need to convert to use. It is already converted.

Anyway, the red crystal methylcobalamin powder.

1 gram = 1,000,000 micrograms. The other person is just .... 1 gram = 1000 mcg and 1000 mcg = 1 mg, then 1 gram = 1,000,000 micrograms. Just move the decimal over 3 places every time for conversions:)
EDIT: Sorry, I think I read that wrong. Depends on how much thinner you add the gram of powder to determine this.

1000.

1000 mcg = 1 mg
1g = 1000 mg
