Question

How do you convert $520mmHg$ to Pa?

Answer 1

Step 1: Given

Pressure = $520mmHg$

Step 2: Millimeters of mercury (mm Hg)

1. Millimeters of mercury (mm Hg) is a non-SI unit of pressure.
2. A pascal (pa) is a SI unit of Pressure.
3. 1 pa = 0.00750062 mm Hg.

Step 3: Conversion of Pa into mm Hg

We know that

$$\begin{gathered} 1pa=0.00750062mmHg. \\ Now,1mmHg=133.322pa. \\ \Rightarrow 520mmHg=133.322\times 520. \\ \Rightarrow 520mmHg=69327pa. \end{gathered}$$

Therefore, 520 mm Hg is equal to 69327 pascals.
