Magnetism converter
Tesla and gauss (flux density).
1 gauss = 0.0001 tesla
How it’s calculated
T = G × 0.0001
- Multiply the value in gauss by 0.0001.
- To go back, divide by 0.0001 (or multiply by 10000).
- 1 G = 0.0001 T · 1 T = 10,000 G

Find the conversion factor
By definition 1 T = 10000 G. Source: NIST SP 811 / Handbook 44; BIPM SI Brochure (9th ed.).
Multiply by the factor written as a fraction
Put G in the denominator so it cancels, leaving T.
Calculate (unrounded)
Round the answer
Rounded to 5 significant figures.
Answer: 0.0001 T
1 G in other units
Batch convert G → T
Results
- 1 G = 0.0001 T
- 5 G = 0.0005 T
- 10 G = 0.001 T
- 25 G = 0.0025 T

tesla (T), millitesla (mT), microtesla (µT), gauss (G), milligauss (mG).
How accurate are the results?
Every unit is stored with its exact defining factor (NIST SP 811, NIST Handbook 44 or the BIPM SI Brochure). Calculations use double-precision arithmetic and are rounded only for display, to 5 significant figures by default (trailing zeros dropped, so 1 km shows as 1000 m). You can choose Auto (up to 10 digits), fixed decimals or more significant figures, or switch to scientific or engineering notation.
