# What is 16.00 kPa in atm?

Recall or look up that $\text{1 atm}$ $=$ $\text{101325 Pa}$.
This means that multiplying by $\text{1 atm"/"101325 Pa}$ merely converts units, and does not change the validity of your answer.
16.00 cancel"kPa" xx (1000 cancel"Pa")/cancel"1 kPa" xx "1 atm"/(101325 cancel"Pa")
$=$ $\textcolor{b l u e}{\text{0.1579 atm}}$ to 4 sig figs.
