How many tanks of gas is a wedding ring?
The gold in a 3.0 g ring of 14 k gold is worth $218.60, which is 4.0 tanks of gasoline today and 4.1 tanks at DataSnack's numbers for seven days from now.
At the gold future's price for pure gold and the US average pump price.
- Now: 4.0 tanks
- In seven days: 4.1 tanks
The working
The value of the gold in a ring at the gold future's price, divided by the cost of one tank of regular gasoline at the US average.
| Step | Expression | Now | In seven days |
|---|---|---|---|
| Gold in the ring | `grams / troy karat / 24 gold` | $218.60 | $224.77 |
| One tank | `tank gas` | $54.71 | $54.18 |
| Tanks of gas | `metal / fill` | 4.0 tanks | 4.1 tanks |

What this cannot tell you
It is the metal's value only: a jeweller buys below it and sells far above it, and the stones and the work are not counted.
