Mega to Giga examples
1 M
1 M × 0.001 = 0.001 G.
10 M
10 M × 0.001 = 0.01 G.
100 M
100 M × 0.001 = 0.1 G.
Mega compared with Giga
One G is 1,000 times as large as one M, so your number gets smaller when you convert mega to giga and bigger when you convert back. If the answer is not smaller than what you typed, you multiplied instead of dividing.
About mega and giga
Mega (M): Mega, 10⁶ (one million). Giga (G): Giga, 10⁹ (one billion).
How to calculate Mega to Giga step by step
- Enter the value in M (the starting unit).
- Multiply by 0.001, because 1 M = 0.001 G.
- The product is the value in G. To go back, divide by 0.001 or multiply by 1,000.

- Dividing when you should multiply: from M to G multiply by 0.001; from G to M divide by 0.001.
Mega to Giga FAQ
How many G are in 1 M?
1 M equals 0.001 G.
How many M are in 1 G?
1 G equals 1,000 M.
Is 1 M = 0.001 G an exact conversion?
Yes. The mega and the giga are both defined exactly in SI terms, so the ratio has no measurement uncertainty; 0.001 is just that ratio shown to 7 significant figures.
What is a giga (G)?
Giga, 10⁹ (one billion).
How can I estimate mega to giga in my head?
One G is 1,000 times as large as one M, so your number gets smaller when you convert mega to giga and bigger when you convert back. If the answer is not smaller than what you typed, you multiplied instead of dividing.
What is 200 M in giga?
200 M = 0.2 G (since 200 × 0.001).
What is 3 M in giga?
3 M = 0.003 G (since 3 × 0.001).
What is 30 M in giga?
30 M = 0.03 G (since 30 × 0.001).
How many decimals should I keep when converting M to G?
Match the precision of your original measurement. For example, 0.01 G rounds to 0.01 G at 3 significant figures; keep more digits only for engineering or scientific work.
