The pressure in Denver, Colorado (elevation 5280 ft), averages about 24.9 in mmHg.

c) Convert this pressure to Pa.

$\boxed{~ 1\ \text{mmHg} = 133.322\ \text{Pa} ~}$

$24.9\ \text{mmHg} = 24.9\cdot 133.322\ \text{Pa}\\ \mathbf{24.9\ \text{mmHg} = 3319.7178\ \text{Pa} }\\$

b) Convert this pressure to psi.

$\boxed{~ 1\ \text{pascal} = 0.00014503773801\ \text{pound force/square inch [psi]} ~}$

$24.9\ \text{mmHg} = 24.9\cdot 133.322\cdot 0.00014503773801\ \text{pound force/square inch [psi]}\\ \mathbf{24.9\ \text{mmHg} = 0.481484360543533578\ \text{pound force/square inch [psi]} }\\$

a) Convert this pressure to atm.

$\boxed{~ 1\ \text{pascal} = 0.0000098692326671601283\ \text{atm} ~}$

$24.9\ \text{mmHg} = 24.9\cdot 133.322\cdot 0.0000098692326671601283\ \text{atm}\\ \mathbf{24.9\ \text{mmHg} = 0.03276306735751295336779374\ \text{atm} }\\$
