Do I understand correctly, that you want the distance from Earth to planet? If the planet is in line with the Sun, to get the distance to Earth you add or subtract the distance from Sun to Earth (about 150 million km.). If the planet is in another direction, it can be anything in between, depending on the angle. You need to use trigonometry in that case.
Do you mean how far are the planets from the Sun in AU?
If so, see related question.
An "astronomical unit" is a measure of distance - based on the distance from the Earth to the Sun. "meters per second" is a measure of speed. These are not convertable one to the other.
The distance between neptune and the sun is 15.0935 astronomical units (AU).
light years
No, because a newton is a measurement of force. You can only convert units that measure the same object. For example you can convert meters to feet because they are both measurements of distance.
The distance from Jupiter to Earth is 4.046 astronomical units or 376.1 million miles or 6.053 x 10^8 kilometers.
Neptune is the remotest of the eight planets, and its distance is 30 astronomical units, which means its distance from the Sun is 30 times the Earth's distance from the Sun.
AU - Astronomical units - Distance from the Earth to the Sun. Approx 93 million miles
1) The astronomical unit is the mean distance from Earth to the Sun only. However you can measure the distance to Mars in these units. 2) Unfortunately, that distance keeps changing as the planets move in their orbits.
You can't. Units of time don't convert to units of distance.
Pluto is approximately 39.5 Astronomical Units from the sun. Whereas the Earth is around1.5 AU from the sun. That is a distance fetween the two planets of around 38 Astronomical Units (AU).
You cannot convert millilitres to metres. Millilitres are units of volume and metres are units of length or distance.
To convert acceleration to velocity, you must integrate.Similarly, to convert velocity to distance, you must integrate a second time. This is why the distance covered by a projectile is a second order quadratic equation.

The units are incompatible and cannot be converted
It's impossible. Nanometers are units of distance and Joules are units of energy.
This distance is continuously varying as the two planets orbit the Sun. The minimum distance is about 0.5 au. That's because the (average) distance of Earth from the Sun is 1 au and the (average) distance of Mars from the Sun is 1.52 au.
I suggest you measure the quarter, then divide the distance from Earth to Sun (150 million kilometers) by this distance. You should convert both units to a common unit first, for example, convert everything to meters, or to millimeters.
