Behold the price of gas in Thailand. Here’s today’s assignment: Tell us the cost for a gallon of gas in Thailand in US dollars. Keep in mind, the prices you are looking at are for a liter. Use your currency convertor to find out how many Thai Baht you get for a US dollar. Then use the well-worn formula for converting liters to gallons. This is just one of the many ways we use our math skills (and our calculator apps) on a constant basis on the road. Is gas in Thailand more or less than where you live?

Note: We usually fill up with 91 octane at home, but when we’re on the road and driving a rental car we tend to put in the cheaper gas — which is 32.78 per liter. (Is that somehow wrong?) Be careful you don’t fill up with the top one — that’s the price of diesel.

Please no math.

check your email and tell me if I got the same answer as Franny.

Here’s Liz’s email:

“Is it $4.094 per gallon?

Now that is useful math!!

Unleaded gas is $3.83 at my regular gas station today”

Yes, Liz! That is approximately correct. And in our world, approximately correct is the same as correct. Our math led us to $4.05 a gallon. Much more expensive than Ecuador, a lot less than Australia!

PLEASE—I’M RETIRED!

I just pay what the sign says in the foreign currency.

I do not convert.

I do not access liter>gallon computer apps.

I do not know what I am paying in dollars.

I do not make myself miserable.

I am ignorant and happy.

We’re with you, Karl. But out of the road, we play these games and they keep our minds sharp. It’s amazing to us how much math — that much maligned subject — comes into use on a constant basis on our journey.

Yes, I understand. Perhaps if I played these calculation games more often, I’d remember where I parked my car at The Beverly Center. Or why I am standing in the kitchen with a large spoon in my hand…

Aren’t we getting the answer? Because I am not going to do the calculations, but now I want to know.

I’m with you Karl, on this issue; but then I can just ask Mark et al to help me out.It is nice to know that all your skills are being sharpened.

Here’s the formula:

Baht per litre x 3.78541 = Price per gallon in Baht

Price per gallon in Baht / current exchange rate to USD = Price per gallon in USD

In this case, 32.78 x 3.78541 = 124.085

124.085 / 30.67 (today’s exchange rate) = $4.04 a gallon

Just for fun, wouldn’t that be an Imperial gallon in Thailand? That would throw another wrinkle into your calculations! Of course you’re very correct: ON THE ROAD, close enough is!!!!!!
