atm a mbar convertitore - Atmosfera standard a Millibar

Conversion derivation

Express both atm and mbar 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 mbar in the base unit

   $$1\mathrm{mbar}=100\mathrm{Pa}$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1\mathrm{atm}& =\frac{101,325\cancel{\mathrm{Pa}}}{100\cancel{\mathrm{Pa}}}\times 1\mathrm{mbar}\\ & =\frac{101,325}{100}\mathrm{mbar}\\ & =1,013.25\mathrm{mbar}\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{mbar}& =\frac{100\cancel{\mathrm{Pa}}}{101,325\cancel{\mathrm{Pa}}}\times 1\mathrm{atm}\\ & =\frac{100}{101,325}\mathrm{atm}\\ & =0.000986923267\mathrm{atm}\end{array}$$
