This converter allows you to convert light hours [lh] to parsecs [pc] or parsecs [pc] to light hours [lh]. 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 hours to parsecs
There are two simple ways to convert light hours [lh] to parsecs [pc]. In the first calculation method, the value in light hours [lh] is divided by the rounded conversion factor of 28,591.0758. The second method multiplies the value in light hours [lh] by the rounded conversion factor of 3.498 * 10-5.
- Parsecs [pc] ≈ light hours [lh] ÷ 28,591.0758
- Parsecs [pc] ≈ light hours [lh] * 3.498 * 10-5
However, rounded conversion values are only suitable for rough conversions, as rounding errors can occur in the calculation result. The most accurate conversion of light hours [lh] to parsecs [pc] can be achieved using the following calculation method.
- Parsecs [pc] = light hours [lh] ÷ 30,857 * 2,053,373 * 5,256 ÷ 1010
Convert parsecs to light hours
Converting parsecs [pc] to light hours [lh] is easy and can be done in two ways. The first method involves multiplication, in which the value in parsecs [pc] is multiplied by the rounded conversion factor of 28,591.0758. The second variant is a division. Here, the value in parsecs [pc] is divided by the rounded conversion factor of 3.498 * 10-5.
- Light hours [lh] ≈ parsecs [pc] * 28,591.0758
- Light hours [lh] ≈ parsecs [pc] ÷ (3.498 * 10-5)
However, rounded conversion values do not allow for exact calculations because rounding errors can occur in the calculation result. The most accurate conversion of parsecs [pc] to light hours [lh] can be achieved using the following calculation method.
- Light hours [lh] = parsecs [pc] * 30,857 ÷ 2,053,373 ÷ 5,256 * 1010
