Comprehensive Tesla to Gauss Conversion Tables
Magnetic flux density is commonly measured in Tesla (T) in the SI system and Gauss (G) in the CGS system. The conversion between these units is fundamental in physics, engineering, and applied sciences.
| Tesla (T) | Gauss (G) | Application Example |
|---|---|---|
| 1 T | 10,000 G | MRI Scanner Magnetic Field |
| 0.5 T | 5,000 G | Industrial Magnet |
| 0.1 T | 1,000 G | Magnetic Stirrer |
| 0.01 T | 100 G | Earth’s Magnetic Field (approximate) |
| 0.0001 T | 1 G | Small Laboratory Magnets |
| 2 T | 20,000 G | High-Field Research Magnets |
| 5 T | 50,000 G | Superconducting Magnets |
| 10 T | 100,000 G | Particle Accelerators |
These values illustrate the practical range of magnetic field strengths encountered in various scientific and industrial applications. The Tesla unit is standard in SI, while Gauss remains prevalent in certain fields, especially in older literature and specific engineering contexts.
Fundamental Formulas for Tesla to Gauss Conversion
Magnetic flux density (B) is measured in Tesla (T) in the International System of Units (SI) and in Gauss (G) in the centimeter-gram-second (CGS) system. The conversion between these units is straightforward but essential for accurate scientific communication.
- Basic Conversion Formula:
- Inverse Conversion:
Where:
- BT = Magnetic flux density in Tesla (T)
- BG = Magnetic flux density in Gauss (G)
The factor 10,000 arises because 1 Tesla equals 10,000 Gauss exactly, as defined by the relationship between SI and CGS units.
Additional Relevant Formulas
In some contexts, magnetic field strength (H) and magnetic flux density (B) are related by the permeability of the medium (μ). While Tesla and Gauss measure B, understanding this relationship is important for advanced applications.
- Magnetic Flux Density and Magnetic Field Strength:
Where:
- B = Magnetic flux density (Tesla or Gauss)
- μ = Magnetic permeability of the medium (H/m in SI)
- H = Magnetic field strength (A/m in SI)
For vacuum or air, μ ≈ μ0 = 4π × 10-7 H/m.
While this formula does not directly convert Tesla to Gauss, it is essential for understanding the physical context of magnetic fields and their measurement.
Real-World Examples of Tesla to Gauss Conversion
Example 1: MRI Scanner Magnetic Field Conversion
Magnetic Resonance Imaging (MRI) machines typically operate at magnetic field strengths of 1.5 Tesla or 3 Tesla. To understand the equivalent field strength in Gauss, the conversion is necessary.
- Given: BT = 1.5 T
- Find: BG
Using the formula:
Similarly, for a 3 Tesla MRI:
This conversion is critical for engineers and medical physicists who may encounter specifications in either unit system.
Example 2: Earth’s Magnetic Field Measurement
The Earth’s magnetic field strength varies between approximately 0.25 to 0.65 Gauss depending on location. To express this in Tesla:
- Given: BG = 0.5 G (average value)
- Find: BT
Using the inverse formula:
This value is often expressed as 50 μT (microtesla), which is a common unit in geomagnetism.
Expanded Technical Insights on Tesla and Gauss Units
Both Tesla and Gauss measure magnetic flux density, but their usage depends on the system of units and application domain. Tesla is the SI unit, defined as one weber per square meter (Wb/m²), where Weber (Wb) is the SI unit of magnetic flux.
Gauss, on the other hand, is part of the CGS system and is defined as one maxwell per square centimeter (Mx/cm²). The maxwell (Mx) is the CGS unit of magnetic flux.
- 1 Tesla = 1 Wb/m²
- 1 Gauss = 1 Mx/cm²
Since 1 Wb = 108 Mx and 1 m² = 104 cm², the conversion factor between Tesla and Gauss is exactly 10,000.
Practical Considerations in Measurement
When measuring magnetic fields, instruments such as Hall effect sensors, fluxgate magnetometers, and SQUIDs (Superconducting Quantum Interference Devices) may report values in Tesla or Gauss depending on calibration and regional standards.
Understanding the conversion ensures interoperability of data and consistency in scientific reporting.
Unit Prefixes and Their Impact
Both Tesla and Gauss units use prefixes to denote multiples or submultiples, which is important for precision and clarity:
| Prefix | Symbol | Multiplier | Example |
|---|---|---|---|
| Milli | m | 10-3 | 1 mT = 10 G |
| Micro | μ | 10-6 | 1 μT = 0.01 G |
| Nano | n | 10-9 | 1 nT = 0.00001 G |
These prefixes allow for expressing magnetic fields ranging from extremely weak geomagnetic fields to intense laboratory-generated fields with precision.
Standards and References for Tesla and Gauss Units
The International System of Units (SI) officially recognizes Tesla as the unit of magnetic flux density, codified by the Bureau International des Poids et Mesures (BIPM). The CGS system, including Gauss, is still used in some scientific literature and engineering fields, especially in magnetics and astrophysics.
