321 mcg ≈ 3.21 × 10^-10 t. To convert micrograms to metric tonnes, divide by 1,000,000,000,000: 321 ÷ 1,000,000,000,000 = 3.21 × 10^-10.
How to convert micrograms to metric tonnes
t = mcg × 0
- 1 mcg = 0 t (and 1 t = 1,000,000,000,000 mcg).
- Multiply the amount by the factor: 321 × 0 = 3.21 × 10^-10.
- Answer: 321 mcg ≈ 3.21 × 10^-10 t (rounded to 6 significant figures).
Shortcut: dividing by 1,000,000,000,000 gives the same result as multiplying by 0.
