| Celsius | <unit> A measurement of temperature (Celsius or Centigrade) that is commonly used in Europe. Normal body temperature is considered to be 37 degrees Celsius or 98.6 degrees Fahrenheit. Body temperature can vary 1/2 degree Celsius above or below 37 C and still be considered normal. Body temperature varies with many factors including level of activity. To convert a Fahrenheit temperature to Celsius use: C = (F-32) x 5/9. To convert a Celsius temperature to Fahrenheit use: F = (C x 9/5) + 32 (13 Nov 1997) |

| Celsius scale | A temperature scale that is based upon the triple point of water (defined to be 273.16 K) and assigned the value of 0.01°C; this has replaced the centigrade scale because the triple point of water can be more accurately measured than the ice point; although, for most practical purposes, the two scales are equivalent.
