How the Microtesla to Millitesla Converter Works

The microtesla to millitesla converter divides any microtesla (μT) input by 1,000 to produce the millitesla (mT) output. A microtesla is 10⁻⁶ tesla and a millitesla is 10⁻³ tesla. The ratio is 1,000.

Earth's magnetic field is approximately 25–65 μT (0.025–0.065 mT). MRI machines operate at 1,500–3,000 mT (1.5–3 T). Household appliance EMF levels are measured in microtesla for safety compliance with ICNIRP guidelines.

Enter a microtesla value and the millitesla result appears instantly. Both fields are bidirectional.

Microtesla to Millitesla Formula

mT = μT ÷ 1,000

The formula is: mT = μT ÷ 1,000. Since micro (10⁻⁶) is 1,000 times smaller than milli (10⁻³), dividing by 1,000 converts μT to mT.

Example: Earth's field at 50 μT = 0.05 mT. An MRI fringe field at 500 μT = 0.5 mT. A neodymium magnet surface field of 300,000 μT = 300 mT.

Frequently Asked Questions

How many microtesla are in 1 millitesla?

There are exactly 1,000 microtesla (μT) in 1 millitesla (mT). To convert μT to mT, divide by 1,000.

What is Earth's magnetic field in microtesla?

Earth's magnetic field ranges from about 25 μT near the equator to 65 μT near the poles, with a global average around 50 μT (0.05 mT or 0.5 gauss).

What is a safe EMF level in microtesla?

The ICNIRP recommends a public exposure limit of 200 μT (0.2 mT) for 50 Hz magnetic fields and 83 μT for 60 Hz fields. Most household appliances produce well below these levels at normal usage distances.

How do I convert millitesla to microtesla?

Multiply by 1,000. For example, 0.05 mT × 1,000 = 50 μT. This converter supports both directions.

What is the relationship between tesla and gauss?

1 tesla = 10,000 gauss. Therefore 1 mT = 10 gauss and 1 μT = 0.01 gauss (10 milligauss). The tesla is the SI unit; gauss is the older CGS unit still used informally.
