The conversion of 5 grams (g) to millibars (mb) results in a value depending on the context, such as pressure or other units. But assuming you meant a pressure measurement, 5 g in terms of mass does not directly convert to mb because they are different kinds of measurement units. Therefore, no direct conversion exists without additional context.
Grams (g) measure mass, which is how heavy an object is, while millibars (mb) measure pressure, indicating force per unit area, often used in weather and atmospheric measurements. Without a specific relation, such as the pressure exerted by a mass in a certain area, the conversion cannot be directly performed. For example, converting a weight to pressure requires knowing the area over which it is distributed.
Conversion Result
Converting 5 grams to millibars cannot be directly performed because they measure different physical quantities. To relate mass to pressure, additional data like area and conditions are necessary.

Conversion Formula
The conversion from grams to millibars depends on the physical context, but generally, to convert a mass (g) to pressure (mb), you need to know the area and the force exerted. Pressure (p) equals force (F) divided by area (A). Since force is weight (mass times gravity), p = (mass * gravity) / area. For example, if 5g is spread over 1 cm2, the pressure can be calculated by converting mass to force and dividing by area. The formula: mb = (mass in grams * 9.81 m/s2) / area in m2, then converting force to mb.
Conversion Example
- Convert 10g distributed over 1 cm2:
- Mass = 10g
- Force = 10g * 9.81 m/s2 = 98.1 mN (millinewtons)
- Area = 1 cm2 = 0.0001 m2
- Pressure = Force / Area = 98.1 mN / 0.0001 m2 = 981,000 Pa
- Convert Pa to mb: 1 mb = 100 Pa, so 981,000 Pa / 100 = 9,810 mb
- Similarly, for 20g over 2 cm2, the pressure calculation follows the same steps, adjusting values accordingly.
Conversion Chart
Below is a chart showing values from -20.0 to 30.0 in g and their approximate equivalent in mb, assuming a fixed area of 1 cm2. Use this to estimate pressure based on mass distributed over that area.
| g | mb |
|---|---|
| -20.0 | -19,620 |
| -15.0 | -14,715 |
| -10.0 | -9,810 |
| -5.0 | -4,905 |
| 0.0 | 0 |
| 5.0 | 4,905 |
| 10.0 | 9,810 |
| 15.0 | 14,715 |
| 20.0 | 19,620 |
| 25.0 | 24,525 |
| 30.0 | 29,430 |
Note: Values are approximate, assuming the area remains constant at 1 cm2. Larger areas reduce pressure, smaller areas increase it.

Conversion Definitions
g: Grams (g) is a metric unit of mass, used to measure the amount of matter in an object. It’s part of the metric system, where 1000 grams equal one kilogram, and it is commonly used in cooking, science, and everyday weight measurements.
mb: Millibar (mb) is a unit of pressure, equal to one-thousandth of a bar, used primarily in meteorology to measure atmospheric pressure. It quantifies the force exerted by the air on a given surface area, typically over weather-related conditions.
Conversion FAQs
How can I relate grams to pressure in atmospheric conditions?
To relate grams to pressure, you need to consider the area over which the mass is distributed. By converting the mass to force (using gravity), then dividing by the surface area, you get pressure in pascals, which can then be converted to millibars.
What additional information do I need to convert grams to mb?
You need the surface area where the mass is applied and the context (such as whether the mass is pressing on a surface). Without knowing the area, it’s impossible to accurately convert mass to pressure in mb because pressure depends on force per unit area.
Is there a standard way to convert weight to pressure for weather prediction?
Generally, weather prediction uses atmospheric pressure measurements directly in mb or hPa, not by converting weight. However, understanding how mass influences pressure involves knowing the altitude, area, and the distribution of the weight of air columns, which is complex and not a simple conversion.
