258.78 mmHg = 0.3405 atm
Full precision:0.3405 atm
Step-by-Step Solution
To convert 258.78 mmhg to atmospheres, we divide by 760.002 because one atmosphere equals exactly 760.002 mmhg.
1 atmosphere = 760.002 mmhg
Since there are 760.002 mmhg in every atmosphere, we divide our value by this factor:
258.78 ÷ 760.002 = 0.3405 atmospheres
So 258.78 mmhg = 0.3405 atmospheres.
Quick check: 0.3405 × 760.002 = 258.78 mmhg
