For those of us with zero math skills, this calculator is easier:to convert C to F:
9.0/5.0 * (tempc + 40.0)) - 40.0
to convert F to C:
5.0/9.0 * (tempf + 40.0)) - 40.0
I can keep in mind that water freezes at 0 Celsius and boils at 100 Celsius, but those numbers in between make my head spin.
Thankfully the online place in Australia where I buy medications for my pets lists the weight ranges on their web site in both US pounds and kilograms, and back in the day used to send out kg to lbs conversion charts to their US customers. I still have one of those charts taped to my refrigerator. Whenever I place an order with them, the receipt they email me lists tomorrow as the date of transaction - it's like time travel! If nothing else, these differences keep life interesting!
