How many microteslas is 1 gauss?

Exactly 100 microteslas (µT) equals 1 gauss (G). The conversion chain is: 1 G = 0.0001 T, and 1 T = 1,000,000 µT, so 1 G = 0.0001 × 1,000,000 = 100 µT.

What is the difference between gauss and microtesla?

Both measure magnetic flux density (B-field). Gauss is the CGS (centimetre-gram-second) unit; microtesla is one millionth of a tesla, the SI unit. The Earth's magnetic field is about 25–65 µT (0.25–0.65 G), a useful anchor for both scales.

Is the conversion exact?

Yes. 1 G = 10⁻⁴ T exactly, and 1 µT = 10⁻⁶ T exactly, so 1 G = 100 µT with no rounding. Results here are limited only by JavaScript's 64-bit floating-point precision.

When would I use microteslas instead of gauss?

Microteslas are preferred in modern SI-based work, geophysics, and environmental magnetic field measurement (EMF). Gauss remains common in older lab equipment datasheets, US industry catalogs, and CGS-based references.

How do I convert microteslas back to gauss?

Divide the microtesla value by 100. For example, 500 µT ÷ 100 = 5 G. Alternatively, multiply the µT value by 0.01.

What is a typical magnetic field strength in these units?

Earth's surface field is roughly 25–65 µT (0.25–0.65 G). A fridge magnet is about 10,000 µT (100 G). An MRI machine at 1.5 T is 1,500,000 µT (15,000 G).
