Convert milligauss (mG) to microtesla (µT) instantly for EMF measurements and magnetic field analysis
1 milligauss (mG) = 0.1 microtesla (µT)
Formula: µT = mG × 0.1

The milligauss (mG) is a unit of magnetic flux density commonly used for measuring electromagnetic fields (EMF) in everyday environments. One milligauss equals one-thousandth of a gauss, which is part of the CGS (centimeter-gram-second) system of units. Milligauss measurements are particularly popular in the United States for EMF safety assessments, home inspections, and occupational health monitoring. Typical household magnetic fields range from 0.5 to 4 mG, while standing directly under high-voltage power lines might expose you to 10-50 mG. EMF meters commonly display readings in milligauss because this scale is convenient for measuring the weak magnetic fields encountered in residential and commercial settings.
Converting milligauss to microtesla is straightforward because the conversion factor is exactly 0.1. This simple relationship exists because 1 gauss equals 100 microtesla, and since a milligauss is 1/1000 of a gauss, it equals 0.1 microtesla.
Example: Convert 25 mG to µT
25 mG × 0.1 = 2.5 µT
Environmental health professionals use milligauss measurements to evaluate electromagnetic field exposure in homes, schools, and workplaces, comparing readings against recommended safety guidelines.
Utility companies and safety inspectors measure magnetic fields around power transmission lines and electrical substations to ensure compliance with exposure standards.
Healthcare facilities measure ambient magnetic fields to ensure compatibility with sensitive medical equipment like MRI machines and pacemakers.
Electronics manufacturers monitor EMF levels during production to prevent interference with sensitive components and ensure product quality.
Scientists studying the biological effects of electromagnetic fields use milligauss measurements in epidemiological research and laboratory experiments.
Milligauss is part of the CGS system traditionally used in the United States, while microtesla is the SI (metric) unit used internationally. Both measure the same physical quantity but use different scales.
While there's no universally agreed-upon safe level, many health organizations suggest limiting continuous exposure to below 2-3 mG (0.2-0.3 µT). However, regulatory standards vary by country and context.
In the United States, milligauss is more commonly used for consumer EMF meters and safety guidelines. Internationally and in scientific publications, microtesla (or tesla) is the standard. Use whichever unit matches your meter or local regulations.
The conversion is exact: 1 mG = 0.1 µT precisely. There is no approximation involved, making the conversion perfectly accurate for all practical purposes.
Yes, Earth's magnetic field is typically around 500 mG (50 µT) at the surface, though it varies by location. This is several orders of magnitude stronger than typical man-made EMF exposures.
Common sources include power lines, electrical panels, appliances (especially motors and transformers), computer monitors, hairdryers, and electric blankets. Readings decrease rapidly with distance from the source.
