What is STP? The STP stands for the standard temperature and pressure of the substance. In chemistry STP is used to calculate the volume of a substance at STP, the standard STP is 273 K or 0° Celsius at the 1 atmospheric pressure. Certain properties of matter and substances also vary with changes in temperature or pressure. The online free volume at STP calculator is a simple way to identify the density, melting, and boiling point of a substance at STP (Standard Temperature and pressure).
