This converter allows you to convert nautical miles [NM] to light seconds [ls] or light seconds [ls] to nautical miles [NM]. Calculations are performed in both directions. The calculation result and the entered value are displayed with up to 20 decimal places for maximum accuracy.

1 nautical mile [NM] ≈ 6.178 * 10-6 light seconds [ls]1 light second [ls] ≈ 161,874.9773 nautical miles [NM]

Convert nautical miles to light seconds

There are two simple ways to convert nautical miles [NM] to light seconds [ls]. In the first calculation method, the value in nautical miles [NM] is divided by the rounded conversion factor of 161,874.9773. The second method multiplies the value in nautical miles [NM] by the rounded conversion factor of 6.178 * 10-6.

  • Light seconds [ls] ≈ nautical miles [NM] ÷ 161,874.9773
  • Light seconds [ls] ≈ nautical miles [NM] * 6.178 * 10-6

However, rounded conversion values are only suitable for rough conversions, as rounding errors can occur in the calculation result. The most accurate conversion of nautical miles [NM] to light seconds [ls] can be achieved using the following calculation method.

  • Light seconds [ls] = nautical miles [NM] ÷ 2,933.39 ÷ 1,022 * 18.52

Convert light seconds to nautical miles

Converting light seconds [ls] to nautical miles [NM] is easy and can be done in two ways. The first method involves multiplication, in which the value in light seconds [ls] is multiplied by the rounded conversion factor of 161,874.9773. The second variant is a division. Here, the value in light seconds [ls] is divided by the rounded conversion factor of 6.178 * 10-6.

  • Nautical miles [NM] ≈ light seconds [ls] * 161,874.9773
  • Nautical miles [NM] ≈ light seconds [ls] ÷ (6.178 * 10-6)

However, rounded conversion values do not allow for exact calculations because rounding errors can occur in the calculation result. The most accurate conversion of light seconds [ls] to nautical miles [NM] can be achieved using the following calculation method.

  • Nautical miles [NM] = light seconds [ls] * 2,933.39 * 1,022 ÷ 18.52
