Good point. In comparing to prices around the world, let us remember that $1.00 per gallon (cheap) and $1.50 per gallon (reasonably expensive) have the following equivalents*: 1.00 $/gal = 0.265 $/L = 26.5 cents per litre (about 25 cents US) 1.50 $/gal = 0.3975 $/L = 39.75 cents per litre (about 40 cents US Other values can be quickly interpolated. All those values, of course, may be reasonably rounded off for committing to memory or to suit the situation. Actually, if sharply rounded, the values can be found just be dividing the $/gal figure by 4; that would be close enough for many uses. Regards, Bill Hooper * I used 1 gal = 4 qts and 1 L = 1.06 quarts in making the conversions. ============ Keep It Simple! Make It Metric! ============
