What is the equivalent of 5 G in mT?

The conversion from gauss (G) to millitesla (mT) is based on the relationship where 1 G equals 0.1 mT. To find the equivalent of 5 G in mT, you can use the conversion factor:

5 G × 0.1 mT/G = 0.5 mT.

Therefore, 5 G is equal to 0.5 mT, making this choice correct. Understanding this conversion is crucial in MRI safety, as it helps ensure that magnetic field measurements are accurately interpreted and effectively communicated in a clinical setting.
