620 ns ≈ 6.2 × 10^-7 s. To convert nanoseconds to seconds, divide by 1,000,000,000: 620 ÷ 1,000,000,000 = 6.2 × 10^-7.
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: 620 × 1 × 10^-9 = 6.2 × 10^-7.
- Answer: 620 ns ≈ 6.2 × 10^-7 s (rounded to 6 significant figures).
Shortcut: dividing by 1,000,000,000 gives the same result as multiplying by 1 × 10^-9.
