      Hi Mike,

      Yes, you will have to adjust your temp readings based on barometric pressures at various altitudes.   There are many charts you can look up for your exact location in both Yahoo and Google.  The lower the barometric pressure, the lower the boiling points of liquids and visa versa.

      Here is a representative scale.  Good Luck.

      Vino es Veritas,

      Jim.

      Here are other values for the boiling point of water a various barometric pressures and the approximate altitudes that corresponds to under normal conditions.

      31 in. Hg: 214 °F or 101.1 °C (at approx -1000 ft or -305 m below sea level)

      30 in. Hg: 212.15 °F or 100 °C (at approx sea level)

      29 in. Hg: 210.3 °F or 99.06 °C (at approx 1000 ft or 305 m above sea level)

      28 in. Hg: 208.44 °F or 98.02 °C (at approx 2000 ft or 610 m above sea level)

      27 in. Hg: 206.59 °F or 96.99 °C (at approx 3000 ft or 914 m above sea level)

      25 in. Hg: 202.89 °F or 94.94 °C (at approx 5000 ft or 1524 m above sea level)

      23 in. Hg: 199.19 °F or 92.88 °C (at approx 7000 ft or 2134 m above sea level)

      21 in. Hg: 195.48 °F or 90.82 °C (at approx 10,000 ft or 3048 m bove sea level)

      19 in. Hg: 191.78 °F or 88.77 °C (at approx 12,000 ft or 3658 m above sea level)

      17 in. Hg: 188.07 °F or 86.71 °C (at approx 15,000 ft or 4572 m above sea level)

      10 in. Hg: 175.11 °F or 79.51 °C (at approx 27,000 ft or 8230 m above sea level)

      5 in. Hg: 165.85 °F or 74.36 °C (at approx 42,000 ft 12,802 m above sea level)

      NOTE: These pressure values are absolute values, as opposed to relative. Many types of pressure gages measure relative pressure (such as the ones used to measure the pressure in bicycle or car tires). However, a barometer measures the absolute pressure (as well as most electronic pressure gages). If using a relative gage, you to find the absolute pressure, you must subtract the outside air pressure from the relative reading (so you must already know the outside air pressure using a barometer).

          Correct Mike,

          But 1% is just a drop or 2 in the bucket (or collection jar :):):).  Once your on your way,  you will find the senses that God gave you will take over, and make your themometer a secondary implement - even along with your Hydrometers..... ;)

          Vino es Veritas,

          Jim.
