Also the central bank has one of the better sites in Chile in English with the daily UF, euro and dollar rates posted along with a mountain of other economic stuff in English.
http://www.bcentral.cl/eng/I use that site all the time to calculate our rates.
Honestly, I at first did not like the UF and thought it would confuse foreigners (it does), but over the last few years using it in our contracts (also keeps me from needing to revise contracts constantly) it has seriously helped stabilize our bottom line from all the ups and downs in the economy (does everyone recall the run in inflation we had a few years ago). It is especially nice for projects that can drag out over years.
I was really shocked a few weeks ago when a client contacted me to go ahead with a project I had previously issued a quote on some time ago, and I had to recalculate the invoice in to U.S. dollars that I had previously quoted about 6 months before using the same UF to pesos to dollar conversion system. Between the UF moving one direction and the dollar really moving the other, it was like a 30% increase in our prices in 6 months for people paying in U.S. dollars. Our prices have in fact stayed the same in UF for like the last three years.
I thought about lowering our prices to compensate, but it is a bunch of macro forces outside both my control and our client's control (a lot of it is just seasonal also). We work, live, and get paid in a peso environment, and my rising or falling cost track the UF fairly closely in pesos. Also on the flip side of that, a client that for example contracts us now in UF also gets the benefits down the road if everything moves the other direction. A couple years ago I was starting to question the use of the UF because the UF was going down, and the dollar was getting stronger. In a high inflation environment, UF is a serious stabilizer overall.
The worthless U.S. dollar however, not sure what to do about that. Suppose I could convert UF to Oz of Gold or silver if anyone wanted to pay that way.
Every time I am offered a consumer loan from my bank in Chile that has the interest calculated in Pesos, I am really tempted to take it because we get paid at UF rates in pesos.
