Convert 1000 Millitesla (mT) to Nanotesla (nT).

1000 Millitesla equals 1,000,000,000 Nanotesla. Multiply 1000 by 1,000,000.

1000 Millitesla = 1,000,000,000 Nanotesla

Worked example: converting Millitesla to Nanotesla

Step 1 — start with the formula. nT = mT × 1,000,000
Step 2 — substitute your figure. 1000 mT × 1,000,000
Step 3 — read the result. 1000 mT = 1,000,000,000 nT
Step 4 — check it in reverse. mT = nT × 0.000001 returns Invalid mT, which matches the figure you started with.
