atm a Pa convertitore - Atmosfera standard a Pascal

Conversion derivation

Express both atm and Pa in the same base unit Pa (pascal), then cancel the shared base unit.

1. 1

   Rewrite atm in the base unit

   $$1\mathrm{atm}=101,325\mathrm{Pa}$$
2. 2

   Rewrite Pa in the base unit

   $$1\mathrm{Pa}=1\mathrm{Pa}$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1\mathrm{atm}& =\frac{101,325\cancel{\mathrm{Pa}}}{1\cancel{\mathrm{Pa}}}\times 1\mathrm{Pa}\\ & =\frac{101,325}{1}\mathrm{Pa}\\ & =101,325\mathrm{Pa}\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{Pa}& =\frac{1\cancel{\mathrm{Pa}}}{101,325\cancel{\mathrm{Pa}}}\times 1\mathrm{atm}\\ & =\frac{1}{101,325}\mathrm{atm}\\ & =0.000009869233\mathrm{atm}\end{array}$$
