# Lingots to gems: how does the math work here?

First of all, down with the health system. It's hardly an improvement.

Second, I have 1616 lingots, which were converted to 2100 gems. Isn't the math a bit off? There's absolutely no chance of this being proportional.

What's the logic behind this conversion?

Cheers.

I'll try but you're better off with himnicholson's explanation.

So let's set up a proportion so 1616 over 2100 which simplified to 404/525. So now let's divide 404 to 525 which is approx. ≈ 0.7695.

Now lets round 0.7695 to the nearest hundredth so it would be 0.77. This is not accurate but for every Gem it is worth 0.77 of a lingot ?

I don't know you're better off with a different explanation. I'm probably wrong and nowhere near the actual maths but this is my way.
