Nanoseconds to Seconds Conversion Formula

Formula:

Seconds = Nanoseconds ÷ 1,000,000,000

Nanoseconds to Seconds Examples

  • 1,000,000,000 ns to s
    Step 1: Formula = s = ns ÷ 1,000,000,000
    Step 2: Substitute = 1,000,000,000 ÷ 1,000,000,000
    Step 3: Result = 1 second
     
  • 500,000,000 ns to s
    Step 1: s = ns ÷ 1,000,000,000
    Step 2: Substitute = 500,000,000 ÷ 1,000,000,000
    Step 3: Result = 0.5 seconds
     
  • 2,500,000,000 ns to s
    Step 1: s = ns ÷ 1,000,000,000
    Step 2: Substitute = 2,500,000,000 ÷ 1,000,000,000
    Step 3: Result = 2.5 seconds

Seconds to Nanoseconds Conversion Formula

Formula:

Nanoseconds = Seconds × 1,000,000,000

Seconds to Nanoseconds Examples

  • 1 second to ns
    Step 1: Formula = ns = s × 1,000,000,000
    Step 2: Substitute = 1 × 1,000,000,000
    Step 3: Result = 1,000,000,000 ns
     
  • 0.25 seconds to ns
    Step 1: ns = s × 1,000,000,000
    Step 2: Substitute = 0.25 × 1,000,000,000
    Step 3: Result = 250,000,000 ns
     
  • 5 seconds to ns
    Step 1: ns = s × 1,000,000,000
    Step 2: Substitute = 5 × 1,000,000,000
    Step 3: Result = 5,000,000,000 ns
