20.2 ns ≈ 2.02 × 10^-8 s. To convert nanoseconds to seconds, divide by 1,000,000,000: 20.2 ÷ 1,000,000,000 = 2.02 × 10^-8.
How to convert nanoseconds to seconds
s = ns × 1 × 10^-9
- 1 ns = 1 × 10^-9 s (and 1 s = 1,000,000,000 ns).
- Multiply the amount by the factor: 20.2 × 1 × 10^-9 = 2.02 × 10^-8.
- Answer: 20.2 ns ≈ 2.02 × 10^-8 s (rounded to 6 significant figures).
Shortcut: dividing by 1,000,000,000 gives the same result as multiplying by 1 × 10^-9.
