I figure I'll understand algebra about the time I retire.
I find that it's best to include the units of measure in the calc. That way when they cancel out, if you are left with the right units, you probably set it up right.

I'll remember that for about the next 6 minutes...math is not my forté, but I do keep trying. If the formula had been evident (to me) I would have just been able to plug in the numbers...

I don't mess around at work, I have all my formulas written down AND I have someone check my answer.

I did too, but Google conversions failed me. I could have converted liters to gallons and pounds to dollars, but unfortunately my brain exploded and got all over the keyboard and screen, so I had to take a break.

I'm generally good at numbers but some days I just don't want to do complex calculations.

oops, steve and taxy are right. about $8.24 at $1.59 for the current exchange rate for british sterling.

that's what i get for trying to do math in my head.



btw, the gas station where i filled up just yesterday at $3.59/gallon was at $3.75/gallon today.

Okay PF, just to show you I have the right stuff:

£1.37/liter * 1.5973 $US/£ * 3.785 liter/galUS = 8.283 $US/galUS

The units on numerators and denominators cancel out except for the final units. All our answers are in the same ballpark depending on the variances in conversion factors.

No wonder all those EU types drive little cars. Driving in the US vs. driving in EU:

my car at $4.25/gal and 17 mpg: 4.25 $/gal * (1/17) gal/mile = $0.25/mile

EU car at 8.29 $/gal and twice the mpg: 8.29 $/gal * (1/34) gal/mile = $0.24/mile

So you can drive a bigger car in US at lower gasoline cost, or drive a small car in EU with double the MPG, and pay about the same cost per mile.

You know, I don't mind having my mistake explained, I acknowledged it several posts back.

What gave you the idea I was explaining your mistake? I was making up for my laziness in not calculating the conversion earlier, and at least demonstrating I can do it if I want.

My post had nothing to do with you beyond responding to your comment implying that I didn't even try. Now I tried.

That's why I asked. I tried using Google conversions with no good result...
That's what I was responding to when I said, "At least I tried."

I sympathize (and cringe) every time I hire a car in the EU.
