Standard Temp and Pressure -- old values (pre-1982) still prevalent

In summary, the conversation discusses the slow adoption of the new criteria of 750.06 torr as the standard for temperature and pressure, despite being introduced 35 years ago. The industry continues to use the old criteria of 273.15K and 760 torr, and the conversation speculates on the reasons behind this slow adoption, including the difficulty of changing standards in science. The conversation also provides a link to an STP calculator for those who may need it.

Okay, my topic doesn't really ask a question but it is surprising to me that the old criteria of 273.15K and 760 torr are still being reported as the standard and very few websites have the "new" criteria of 750.06 torr.
Are scientists, webmasters, etc. usually this slow at adopting changes? (Well, it has "only" been 35 years.)

Thanks for the quick replies. Still, you would think that after 35 years, there would be some kind of cooperation.

Well in my personal opinion, yes scientists are slow to adapt to new standards, but there is a practical reason to it. Since science develops above fundamental theories and experiments that people few decades or even centuries ago developed. To change a standard is sometimes extremely difficult since all of these previous theories and experiments needs to be reevaluated. I don't think, for practical reason, quickly changing standards is a good idea unless it is really really necessary.

For example, electric current flows from + to -, but electrons are actually moving the opposite way. It is going to be quite a pain to revise this, especially considering the long history of electrochemistry.

Related to Standard Temp and Pressure -- old values (pre-1982) still prevalent

1. What are the old standard temperature and pressure values?

Before 1982, the standard temperature was 0°C (32°F) and the standard pressure was 1 atmosphere (atm). These values were used as a reference for scientific experiments and measurements.

2. Why were these values considered standard?

The standard temperature and pressure values were chosen because they were easily reproducible and provided a consistent baseline for scientific experiments. They were also within the range of common environmental conditions.

3. Are these values still commonly used today?

No, these values are no longer considered standard as they were replaced by the current standard temperature of 25°C (77°F) and pressure of 1 bar. However, the old values may still be used in some industries or for historical purposes.

4. How do the old and new standard values differ?

The main difference between the old and new standard values is the temperature. The old standard temperature of 0°C (32°F) is much lower than the current standard temperature of 25°C (77°F). This change was made to reflect more realistic and commonly encountered temperatures.

5. Why was there a need to change the standard values?

The change in standard values was made to better reflect real-world conditions and improve the accuracy and precision of scientific measurements. The old values were also not consistent with the International System of Units (SI) and the new values align with SI units.
