Oersteds to millitesla in free space

Type a value in Oe to get it in mT instantly.

0.1mT

That's 1.99× as strong as the Earth’s field, while a fridge magnet is 50× stronger. In free space that would make about 100 µT.

What it means

How strong is that field?

H and B are only proportional in free space. Inside iron, the same H produces hundreds or thousands of times more B.

The math
