Flour apparently has the density of 125g/cup, and there are 48 teaspoons in a cup. So, 125g/cup * 1000mg/ 1 gram * 1 cup/48 teaspoons = 2604.166667mg/ teaspoon
Milligrams can't be converted to teaspoons. Milligrams measure mass, while teaspoons measure volume.
No, 2.6mcg does not equal 1000mg. 1000mg is equivalent to 1g, so 2.6mcg is a much smaller amount than 1000mg.
1g = 1000mg 17g x 1000mg/g = 17000mg
1g = 1000mg 10mg x 1g/1000mg = 0.01g
1g = 1000mg 215g x 1000mg/g = 215000mg
1g = 1000mg 10mg x 1g/1000mg = 0.01g
0.001kg is 1000mg
One gram is 1000mg
1000mg
1000MG
1000mg = 1g
