If a cough syrup contains 0.24 gm of codeine in 120 ml, how many mg are contained in each teaspoonful

How many mL in a teaspoon? 4.93 mL according to Google.com.
So 0.24 g x 4.93/120 = g in a teaspoon of the syrup. Now convert g to mg by multiplying by 1000. Check my thinking.
OR, type 0.24 g/120 mL to g/teaspoon into google and google's answers will be in g. Multiply by 1000 to convert to mg.
