If it's 0 degrees centigrade today and twice as cold tomorrow, what's the temperature tomorrow?

It depends what you mean by "twice as cold".  Without any further direction given, I would probably move to an absolute scale (Kelvin, in this case), and cut it in half.  The reason for this is that 0 Kelvin is "absolute zero", where there is no heat at all.\n\nK = C + 273\n\nThis would give:\n\n0C = 273K\n\n273K/2 = 136.5K\n\n136.5K = -136.5C\n\nSo I would say -136.5 degrees centigrade.\n\nTo be honest, I've never heard of weather getting that cold before...

That depends entirely on whether you mean 0 degrees Kelvin, 0 degrees Fahrenheit or 0 degrees Celsius.\n\nOnce you tell us that the answer will be very easy to work out. Only the Kelvin scale allows us to refer to temperatures  as fractions of other temperatures, so any reading will need to be converted to Kelvin with reference to absolute zero.\n\nIt's really not hard to do, but you need to tell us your units.

0°C = 32°F\nSo instead of going with 0°C, go with 32°F, so that would be 32 * 2 = 64°F or about 18°C\n\nBut if you are talking about 0°F, which is about -18°C, double that and you get -32°F\n\nSo you either get about 18°C or -32°F

Mmmmm, methinks this is a trick question but I will guess at minus 2 degrees...;

It depends what degrees you're talking about. For example, if it were 0 degrees in Celsius, that's 32 degrees Farenheit, and twice as cold would logically be 16 degrees Farenheit. But 0 degrees Celsius is also 273 degrees Kelvin, and twice as cold would be 136.5 degrees Kelvin. I guess in this case, the units of measure really matter.

29.444..°C\n\nC = (F - 32) * (5/9)\nC = (85 - 32) * (5/9)\nC = 53 * 5/9\nC = 265 / 9\nC = 29 4/9° C

One answer would be to convert 0C into 273 Kelvin or 32 F and then do some multiplication.\n\nBut "cold" is really a subjective measure based on physiology. I suspect if you did a test with actual humans you would find that around -10.6 C feels twice as cold as 0 C.\n\nThat is what this wind chill calculator finds, if wind speed is always zero.

It's generally around 62- 68 degrees.\n\nThat's Fahrenheit,not Celsius !

Go with a line graph, that way you can also find out (or estimate) temperatures at times when you didnt measure it.

Nonsensical question - nobody can answer this.  And nobody ever says "twice as cold" simply because they know it is meaningless.\n\nThermo, your calculations (below) are WRONG.

at 1atm it's 212 F or 100C.  That's only at 1atm.
