The Gauss (G) is a unit of magnetic flux density in the CGS (centimeter-gram-second) system, named after mathematician Carl Friedrich Gauss. It measures the strength of magnetic fields and is commonly used for weaker magnetic fields. One Gauss equals 0.0001 Tesla, making it suitable for measuring smaller magnetic fields like those of refrigerator magnets (50-100 G) or the Earth's magnetic field (0.25-0.65 G). While Tesla is the preferred SI unit, Gauss remains popular in industry and everyday applications due to its convenient scale for common magnetic field strengths.
Formula: Tesla = Gauss × 0.0001
Steps:
Example: Convert 25,000 Gauss to Tesla
25,000 G × 0.0001 = 2.5 T
1 Gauss equals exactly 0.0001 Tesla (or 1/10,000 Tesla).
Gauss provides more convenient numbers for everyday magnetic fields, avoiding very small decimal values.
A typical refrigerator magnet has a field strength of 50-100 Gauss (0.005-0.01 Tesla).
Earth's magnetic field ranges from about 0.25 to 0.65 Gauss depending on location.
Gauss is part of the CGS system. Tesla is the metric SI unit, but Gauss is still widely used.
Yes, they measure the same property. Just remember to convert: 1 T = 10,000 G.
