SI Tesla Prefix Converter (nT, µT, mT, T)
to = from × 10^(fromExp − toExp) on teslas.
Earth’s field is tens of microteslas. Fridge magnets are milliteslas. MRI is teslas. A 50 µT quiet-room reading is 0.05 mT. Gauss is 10⁻⁴ T — not a prefix, a different system.

How this calculator works
Earth’s field is tens of microteslas. Fridge magnets are milliteslas. MRI is teslas. A 50 µT quiet-room reading is 0.05 mT. Gauss is 10⁻⁴ T — not a prefix, a different system. to = from × 10^(fromExp − toExp) on teslas. Example: 50 µT → 0.05 mT → 5×10⁻⁵ T. A 1.5 T MRI magnet is 1,500 mT.
to = from × 10^(fromExp − toExp) on teslas.
Example: 50 µT → 0.05 mT → 5×10⁻⁵ T. A 1.5 T MRI magnet is 1,500 mT.
When to use this SI Tesla Prefix
Common use cases
- Earth’s field is tens of microteslas. Fridge magnets are milliteslas. MRI is teslas. A 50 µT quiet-room reading is 0.05 mT. Gauss is 10⁻⁴ T — not a prefix, a different system.
- Sanity-check with this case: 50 µT → 0.05 mT → 5×10⁻⁵ T. A 1.5 T MRI magnet is 1,500 mT.
- The relationship is: to = from × 10^(fromExp − toExp) on teslas.

What you get
- Fields: From prefix
- to = from × 10^(fromExp − toExp) on teslas.
- Example on the page: 50 µT → 0.05 mT → 5×10⁻⁵ T. A 1.5 T MRI magnet is 1,500 mT.
How to Convert SI Tesla Prefix Step-by-Step
- 1Enter From prefix. Use the values you have, not a catalog average, unless that is all you know.
- 2to = from × 10^(fromExp − toExp) on teslas.
- 3Worked case: 50 µT → 0.05 mT → 5×10⁻⁵ T. A 1.5 T MRI magnet is 1,500 mT.
- 4Check which dictionary the other person is using — US or UK, decimal or 1,024 — then trust the number.
Governing formula
to = from × 10^(fromExp − toExp) on teslas.
50 µT → 0.05 mT → 5×10⁻⁵ T. A 1.5 T MRI magnet is 1,500 mT.
Example: set From prefix = 50, then read the result.
Variable definitions
- value
From prefix
The “From prefix” field. Default 50; typical range 0–1e+24.
- The conversion (to = from × 10^(fromExp − toExp) on teslas.) does not pick US vs UK gallons, SI vs binary megabytes, or Mach at altitude for you. Read the footnote on the page.
- Nothing here is uploaded for the calculation itself.
Frequently Asked Questions
1 G = 10⁻⁴ T = 100 µT. Convert gauss separately; do not pick a fake “giga” prefix.

- SI Ampere Prefix ConverterLED strings in milliamps, lab picoammeters, and utility kiloamperes share one ampere. A 20 mA loop is 0.02 A. Fuses are labeled in the prefix the catalog bought, not the one your meter displays.
- SI Coulomb Prefix ConverterCharge is current times time, but the unit still prefixes like the others. Battery milliamphours are a different dictionary (1 mAh = 3.6 C). Use this when a spec already wrote coulombs.
- SI Farad Prefix ConverterA one-farad cap is a small brick. Everyday ceramics are picofarads and nanofarads; electrolytics are microfarads. Datasheets hop prefixes without warning. Convert before you order the wrong reel.
- SI Gram Prefix ConverterMass prefixes attach to the gram, not the kilogram. Kilogram is already kilo + gram. Scale yottagram down to yoctogram, or milligram to microgram, without mixing in pounds. Jewelry carats and troy ounces are separate legal pages.
- SI Henry Prefix ConverterPower inductors are millihenrys. RF chokes are microhenrys. A 1 H inductor is an audio-era doorstop. Scale the prefix; this is not an impedance-at-frequency calculator.
- SI Hertz Prefix ConverterAudio A4 is 440 Hz. FM radio lives in megahertz. Wi-Fi and CPUs argue in gigahertz. IR spectroscopy climbs into terahertz. Same hertz, different zeros. This grid also covers millihertz if you are watching a very slow oscillator.

Unit Converters
A 5K is 5,000 meters, not 5 kilometers on the nose if your watch is sloppy. Divide meters by 1,000. Track races, building plans, and “how far was that hike” all live in this split.
Feet to Meters
Unit Converters
US height, ceiling height, and lumber still arrive in feet. Meter plans do not. One foot is exactly 0.3048 m — not “about a third.” Use this when a listing says 10 ft ceilings and the architect works in meters.
Inches to Centimeters
Unit Converters
Monitor diagonals, waist measurements, and photo prints still come in inches. Clothing charts in Europe come in cm. Multiply inches by 2.54. That factor is exact, not a kitchen guess.

Very usable on mobile. Would love a save/export option later, but the math feels solid.
