This converter allows you to convert light days [ld] to light seconds [ls] or light seconds [ls] to light days [ld]. Calculations are performed in both directions. The calculation result and the entered value are displayed with up to 20 decimal places for maximum accuracy.
Convert light days to light seconds
There are two simple ways to convert light days [ld] to light seconds [ls]. In the first calculation method, the value in light days [ld] is divided by the rounded conversion factor of 1.157 * 10-5. The second method multiplies the value in light days [ld] by 86,400.
- Light seconds [ls] ≈ light days [ld] ÷ (1.157 * 10-5)
- Light seconds [ls] = light days [ld] * 86,400
The calculation method with a rounded conversion value is more suitable for rough conversions from light days [ld] to light seconds [ls], as the calculation result may contain rounding errors. Therefore, the variant with the exact conversion factor is more suitable.
Convert light seconds to light days
Converting light seconds [ls] to light days [ld] 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 1.157 * 10-5. The second variant is a division.
