Mega to Nano formula and what each symbol means
n = M × 1×10¹⁵
| Symbol | Meaning |
|---|---|
| M | Mega |
| n | Nano |
Mega to Nano examples
1 M
1 M × 1×10¹⁵ = 1×10¹⁵ n.
10 M
10 M × 1×10¹⁵ = 1×10¹⁶ n.
100 M
100 M × 1×10¹⁵ = 1×10¹⁷ n.
Mega compared with Nano
One M is 1×10¹⁵ times as large as one n, so your number gets bigger when you convert mega to nano and smaller when you convert back. If the answer is not larger than what you typed, you divided instead of multiplying.
About mega and nano
Mega (M): Mega, 10⁶ (one million). Nano (n): Nano, 10⁻⁹ (one billionth).
How to calculate Mega to Nano step by step
- Enter the value in M (the starting unit).
- Multiply by 1×10¹⁵, because 1 M = 1×10¹⁵ n.
- The product is the value in n. To go back, divide by 1×10¹⁵ or multiply by 1×10⁻¹⁵.

Mega to Nano FAQ
How many n are in 1 M?
1 M equals 1×10¹⁵ n.
How many M are in 1 n?
1 n equals 1×10⁻¹⁵ M.
Is 1 M = 1×10¹⁵ n an exact conversion?
Yes. The mega and the nano are both defined exactly in SI terms, so the ratio has no measurement uncertainty; 1×10¹⁵ is just that ratio shown to 7 significant figures.
What is a nano (n)?
Nano, 10⁻⁹ (one billionth).
How can I estimate mega to nano in my head?
One M is 1×10¹⁵ times as large as one n, so your number gets bigger when you convert mega to nano and smaller when you convert back. If the answer is not larger than what you typed, you divided instead of multiplying.
What is 80 M in nano?
80 M = 8×10¹⁶ n (since 80 × 1×10¹⁵).
What is 500 M in nano?
500 M = 5×10¹⁷ n (since 500 × 1×10¹⁵).
What is 15 M in nano?
15 M = 1.5×10¹⁶ n (since 15 × 1×10¹⁵).
How many decimals should I keep when converting M to n?
Match the precision of your original measurement. For example, 1×10¹⁶ n rounds to 1×10¹⁶ n at 3 significant figures; keep more digits only for engineering or scientific work.
