I need to store data.
I'd like to store them in Metric units and use a tool to convert them to and from other units that these data points will be displayed in.
As the title states, my constraints are Distance, Pressure, and Temperature.
Distance I know, but it is added here as an example: I store the data in meters and convert to feet where needed.
What are the metrics unit for storing Pressure and Temperature?
Further, I am assuming here that metric units would be the most universal. If there is a more universal unit for Distance, Pressure or Temperature, please let me know.
