Converting 500 mb to inches results in approximately 19.685 inches.
Table of Contents
This conversion is based on translating millibars, a pressure measurement, into inches of mercury (in Hg). Since 1 mb equals approximately 0.02953 inches Hg, multiplying 500 mb by this factor yields the height in inches. It helps in understanding pressure differences in a more visual, linear measure.
Conversion Result and Explanation
500 millibars equal about 19.685 inches of mercury. This means that a pressure of 500 mb is equivalent to a height of roughly 19.685 in in a mercury barometer. This conversion helps visualize atmospheric pressure levels in a more tangible way, especially for weather related interpretations.

Conversion Formula
The conversion from mb to in involves multiplying the pressure value in millibars by 0.02953, because 1 mb equals approximately 0.02953 inches of mercury. This works because inches of mercury measures atmospheric pressure, and the factor converts pressure units accordingly. For example, 500 mb times 0.02953 gives 14.765 inches Hg.
Conversion Example
- Convert 600 mb to in:
- Multiply 600 by 0.02953
- 600 x 0.02953 = 17.718 in
- Pressure of 600 mb is approximately 17.718 inches Hg
- Convert 450 mb to in:
- Multiply 450 by 0.02953
- 450 x 0.02953 = 13.289 in
- Pressure of 450 mb is approximately 13.289 inches Hg
- Convert 525 mb to in:
- Multiply 525 by 0.02953
- 525 x 0.02953 = 15.522 in
- Pressure of 525 mb is approximately 15.522 inches Hg
- Convert 480 mb to in:
- Multiply 480 by 0.02953
- 480 x 0.02953 = 14.190 in
- Pressure of 480 mb is approximately 14.190 inches Hg
- Convert 510 mb to in:
- Multiply 510 by 0.02953
- 510 x 0.02953 = 15.075 in
- Pressure of 510 mb is approximately 15.075 inches Hg

Conversion Definitions
mb (millibar) is a unit of atmospheric pressure measuring the force exerted by air molecules over a specific area, typically used in meteorology. 1 mb equals 100 pascals, and it indicates the pressure level in weather systems or altimeter readings in aviation.
In (inches of mercury) is a unit of pressure measurement based on the height of mercury in a barometer, commonly used in weather reporting and aviation. It reflects how high mercury rises in a glass tube under certain pressure conditions, with 1 in Hg equal to 25.4 mm Hg.
Conversion FAQs
How accurate is the conversion from mb to inches?
The conversion relies on a fixed factor of 0.02953 inches per mb, which provides a close approximation. Minor variations can occur depending on measurement conditions, but for general meteorological purposes, this is sufficiently precise.
Can I use this conversion for altimeter settings?
Yes, altimeter settings are often expressed in inches of mercury, and converting from mb helps pilots and meteorologists understand pressure readings across different measurement systems. Be mindful of the specific context for accurate interpretation.
Why do atmospheric pressure measurements vary between mb and in Hg?
The difference stems from the units’ origins; mb measures force over area, while in Hg measures the height of a mercury column. The conversion factor bridges these units, allowing pressure to be expressed in a linear, visual height measure.
