About Celsius and Fahrenheit temperature conversions
Celsius or Centigrade is the metric system measuring unit for temperature. It was originally defined based on the freezing point of water (0°C) and the boiling point of water (100°C), both at a pressure of one standard atmosphere. The contemporary definition of °C is based on absolute zero and the triple point of specially purified water.
°C = (°F - 32) x 5/9
Fahrenheit is the measuring unit for temperature officially used in the Bahamas, Belize, the Cayman Islands, Palau and the United States. It was originally defined based on the lowest temperature to which brine could reproducibly be cooled (0°F) and the average human core body temperature (100°F). The contemporary definition of °F is based on the temperature at which water freezes (32°F) and the boiling point of water at a pressure of one standard atmosphere.

Pressure and volumetric flow
Careful consideration needs to be given to measuring volumetric flow at standard or reference conditions versus measuring volumetric flow at non-standard conditions. Flow sensors are generally calibrated for specific reference conditions related to particular technical fields. For example, the gas industry references flow volumes based on a temperature of 70°F. Also, it is not uncommon for sensors to be designed to measure mass flow. In these situations both temperature and pressure ranges need to be included when calculating volumetric flow. The following chart is a collection of useful conversions related to pressure and simple volume based flow rates.
