Finding Jupiter's L1

What is the distance to the sun of the Jupiter-Sun system's L1 point in km or AU?

More questions: Is it out of the Asteroid Belt? Would it be a good staging point for low delta-v trips to Jupiter, its trojans, or Mars?

I've googled, and get nice explanations of what a Lagrange point is, how the asteroid belt formed, what the trojans are, but no numbers, alas.

Best answer: Wikipedia lists the Sun-Jupiter L1 point as 726.45×10^9 m, about 726 million km (4.85 AU) from the Sun. This figure is 6% smaller than the Sun-Jupiter distance (which is 5.2 AU). You can see the L1 and L2 points inside and outside each orbit to scale in this chart.

The asteroid belt is in the region between 2 and 3.3AU.
