How This Tool Works
Choose a category — Select Flux Density, Magnetic Flux, or Field Strength.
Enter a value and units — Input the number and select the 'from' and 'to' units.
Click Convert — The tool instantly calculates and displays the result.
Explore further — Use the slider to test different values or copy/share your result.
Converted = Input × (Factor_from / Factor_to) 💡 Each unit has a conversion factor to the SI base unit. 📊 The tool uses precise factors from NIST.
The Physics Behind the Tool
1 T = 1 Wb/m² = 10⁴ G
1 G = 10⁻⁴ T
1 Wb = 10⁸ Mx
1 Mx = 10⁻⁸ Wb
1 A/m = 4π × 10⁻³ Oe ≈ 0.012566 Oe
1 Oe = 1000/(4π) A/m ≈ 79.577 A/m
In vacuum: B = μ₀H, where μ₀ = 4π × 10⁻⁷ H/m. In materials: B = μH, where μ is the permeability. These conversions are essential in electromagnetism, motor design, and magnetic materials research.
Real-World Examples
