Weber/Square Centimeter (Wb/cm²)
Definition: A mixed-scale unit equal to one weber of flux spread over just one square centimeter of area — since a square centimeter is 10⁻⁴ of a square meter, this is a much more concentrated flux density, equal to 10,000 tesla.
History: It arises when an SI flux figure (weber) is combined with a smaller, CGS-scaled area (square centimeters), a combination seen when comparing SI and CGS conventions side by side.
Current use: Rarely encountered in practice given how enormous 10,000 tesla is as a flux density — it mainly appears in derivations that explicitly compare weber-based and CGS-area-based figures.
Weber/Square Inch (Wb/in²)
Definition: A mixed-unit flux density equal to one weber of flux spread over one square inch of area, used to translate SI flux figures into the imperial area units still common in some American engineering contexts.
History: It combines the SI weber with the imperial square inch, a hybrid that arises specifically when working with American engineering drawings or datasheets that mix SI flux units with imperial dimensions.
Current use: Occasionally used in legacy American electrical machine specifications where core flux is given in webers but pole-face area is dimensioned in inches.

About These Parameters
- Value
- The amount of magnetic flux density you want to convert, expressed in the "From" unit. Accepts decimals, and can represent anything from Earth's weak field (a fraction of a gauss) to an MRI machine's several tesla.
- From Unit
- The unit your input value is currently measured in — an MRI or electromagnet's tesla rating, a permanent magnet's gauss rating, or a geomagnetic survey's gamma reading.
- To Unit
- The unit you want the result converted into. Use the swap button to flip From and To instantly, which is handy when translating a gauss-rated permanent magnet's strength into the modern SI tesla or vice versa.
How Magnetic Flux Density Conversion Works
The Formula
Every unit here is defined by a fixed multiplier relative to the tesla. To convert a value from one unit to another:
result = value × (factor of "From" unit ÷ factor of "To" unit)
For Weber/Square Centimeter → Weber/Square Inch: multiply by 6.4516. For example, 1 Wb/cm² × 6.4516 = 6.4516 Wb/in².
Flux Density B vs. Field Strength H
Flux density (B, tesla or gauss) and field strength (H, ampere/meter or oersted — see the related Magnetic Field Strength converter) are often used interchangeably in casual speech, but they measure different things. Field strength is the magnetizing force a coil applies from its current and geometry alone. Flux density is how the field actually turns out once a material responds to that force — inside an iron or ferrite core, B can be thousands of times larger than H alone would predict, because the material's own magnetization adds to the applied field. In empty space, the two are simply proportional by a universal constant.
Tesla, Gauss, and Everyday Magnet Strength
A tesla is a large field by everyday standards — MRI scanners run 1.5-3 T, and powerful research electromagnets can reach into the tens of tesla. Compare that to Earth's own field, only about 0.00005 T (roughly 500 milligauss, or 0.5 gauss) at the surface, and it's easy to see why the gauss remains the practical, human-scaled unit for describing refrigerator magnets, compass calibration, and consumer magnetometers — nobody wants to describe a small craft magnet's strength as "0.001 tesla" when "10 gauss" reads far more naturally.
Example
A magnetic flux density of 1 Wb/cm² equals 6.4516 Wb/in². For scale, Earth's surface field is roughly 0.00005 tesla (about 0.5 gauss, or 50,000 gamma), a small refrigerator magnet is typically a few hundred gauss, and a clinical MRI machine runs at 1.5 to 3 tesla — thirty to sixty thousand times stronger than Earth's own field.
Frequently Asked Questions
How many Webers/Square Inch are in 1 Weber/Square Centimeter?
1 Weber/Square Centimeter (Wb/cm²) equals exactly 6.4516 Webers/Square Inch (Wb/in²).
What's the difference between tesla and gauss?
They measure the same quantity, magnetic flux density, just at different scales: 1 tesla equals 10,000 gauss. Tesla is the modern SI unit used in physics and engineering (MRI machines, electromagnets), while gauss is the older CGS unit that's stuck around for everyday magnets and consumer devices because it produces more human-scaled numbers for typical field strengths.
How strong is Earth's magnetic field compared to a refrigerator magnet?
Earth's surface field is only about 0.5 gauss, while a typical refrigerator or craft magnet is around a few hundred gauss — hundreds of times stronger than Earth's own field, which is exactly why a small magnet can easily override a compass needle held nearby.
Why do geophysicists use gamma instead of tesla or gauss?
Earth's magnetic field and its local variations are measured in nanotesla-scale increments, and describing a field of "0.00005 tesla" or its small local anomalies in tesla or gauss gets unwieldy with all the leading zeros. Gamma (10⁻⁹ tesla) gives geomagnetism and mineral-survey researchers whole, human-readable numbers — Earth's field typically reads as 25,000 to 65,000 gamma depending on location.
Is magnetic flux density the same as magnetic field strength?
Not technically, though the terms are often used loosely as if they were. Flux density (B, tesla/gauss) is how strong the actual magnetic field is, including any contribution from a magnetized material. Field strength (H, ampere/meter or oersted) is only the magnetizing force applied by a coil's current, independent of any material's response. See the related Magnetic Field Strength converter for the H side of this relationship.
