Play hot and cold!

The Rare Thermometer Necklace is a FULLY functioning round liquid-filled Celsius thermometer pendant. It is mercury free and so gorgeous. The thermometer measures 20mm or approximately 3/4in and is set on a custom sterling silver bezel cup and attached to a sterling silver chain.

The 2-link style comes with a 3mm thick flat oval link chain that measures approximately 19in, but I can shorten to size. I think the Rare Thermometer Necklace looks really great as a choker too.

The temperature ranges from -20˚F to 50˚C. Shouldn't you already know the metric system anyways from school?

To convert Celsius to Fahrenheit, multiply by 1.8 and add 32:

F = (C x 1.8) + 32

In case you flunked math, here is a quick conversion:

Celsius Fahrenheit
-20˚C = -4˚F
-10˚C = 14˚F
0˚C = 32˚F
10˚C =  50˚F
20˚C = 68˚F
30˚C = 86˚F
40˚C = 104˚F
50˚C = 122˚F

The Rare Thermometer Necklace is a great conversations starter. Go ahead, talk about the weather!

I also have a Fahrenheit version of this necklace. Please see my other listing or contact me if YOU don't see it. The Rare Thermometer Necklace comes in a gift tin with a tag that states, "YOU are Soooooo HOT!" and a conversion chart.
