I think it’s Nanoscale :)) I’m 99% sure it is
Answer:
Fahrenheit
Explanation:
Scientists would use Kelvin, and occasionally, Celsius scales. They do this because they need a scale that goes Sub-zero. Sub-zero temperatures are below 0° centigrade or, in the United States, below 0° Fahrenheit.

when we convert 32.5 lb/in² to atmosphere, the result obtained is 2.21 atm
<h3>Conversion scale</h3>
14.6959 lb/in² = 1 atm
<h3>Data obtained from the question</h3>
- Pressure (in lb/in²) = 32.5 lb/in²
- Pressure (in ATM) =?
<h3>How to convert 32.5 lb/in² to atm</h3>
14.6959 lb/in² = 1 atm
Therefore
32.5 lb/in² = 32.5 / 14.6959
32.5 lb/in² = 2.21 atm
Thus, 32.5 lb/in² is equivalent to 2.21 atm
