Millibars (mbar)

mbar

1 atm = 1013.25 mbar

Full precision:1013.25 mbar

Step-by-Step Solution

To convert 1 atmospheres to millibars, we multiply by 1013.25 because one atmosphere equals exactly 1013.25 millibars.

1 atmosphere = 1013.25 millibars

Since each atmosphere contains 1013.25 millibars, we multiply our value by this factor:

1 × 1013.25 = 1013.25 millibars

So 1 atmospheres = 1013.25 millibars.

✓Quick check: 1013.25 ÷ 1013.25 = 1 atmospheres

How to Convert Atmospheres to Millibars

To convert atmospheres to millibars, multiply the value by 1013.25.

Millibars = Atmospheres × 1013.25

1 atmosphere = 1013.25 millibars

Tip: To convert millibars back to atmospheres, divide by 1013.25.

Example 1: 1 atm = 1013.25 mbar
1 × 1013.25 = 1013.25

Example 2: 5 atm = 5066.25 mbar
5 × 1013.25 = 5066.25

Example 3: 10 atm = 10132.5 mbar
10 × 1013.25 = 10132.5
