How many gauss is 1 microtesla?

Exactly 0.01 gauss (G) equals 1 microtesla (µT). The derivation: 1 µT = 10⁻⁶ T, and 1 T = 10,000 G, so 1 µT = 10⁻⁶ × 10,000 = 0.01 G.

What is the difference between microtesla and gauss?

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

Is the conversion exact?

Yes. 1 µT = 10⁻⁶ T exactly, and 1 G = 10⁻⁴ T exactly, so 1 µT = 0.01 G with no rounding. Results here are limited only by JavaScript's 64-bit floating-point precision.

When would I use gauss instead of microteslas?

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

How do I convert gauss back to microteslas?

Multiply the gauss value by 100. For example, 5 G × 100 = 500 µT. This is the inverse of the µT → G conversion.

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).

Summary

This converter turns any microtesla value into gauss in real time using the exact factor 1 µT = 0.01 G (since 1 T = 10,000 G and 1 T = 1,000,000 µT, so 1 µT = 0.000001 T × 10,000 G/T = 0.01 G). All math runs in your browser — no server call needed. Alongside the numeric result you get the full formula and a reference table of common magnetic field strengths to put the number in context.
