Convert Microwebers to Milliwebers (µWb to mWb)
1 microweber (µWb) = 0.001 milliwebers (mWb). 1 mWb = 1000 µWb. Example: 15 µWb = 15 × 0.001 = 0.015 mWb.

How to Convert Microweber to Milliweber
- 1 µWb = 0.001 mWb
- 1 mWb = 1000 µWb
- Example: convert 15 µWb to mWb: 15 µWb = 15 × 0.001 mWb = 0.015 mWb
Formula
mWb = µWb ÷ 1000
Derivation from SI units:
- 1 µWb = 10⁻⁶ Wb
- 1 mWb = 10⁻³ Wb
- 1 µWb = 0.000001 Wb ÷ 0.001 Wb per mWb = 0.001 mWb
Both units are defined exactly, so the factor is exact. Microweber definition: microweber; Milliweber definition: milliweber.
Worked examples
- A reading of 10 µWb converts to 0.01 mWb.
10 µWb × 0.001 = 0.01 mWb - A value of 200 µWb is 0.2 mWb.
200 µWb × 0.001 = 0.2 mWb

Where it's used
Microwebers are used for fluxmeter and Helmholtz coil measurements of magnets, while milliwebers appear in transformer core flux per turn. Both measure magnetic flux, so the conversion is a fixed factor.

Frequently asked questions
How many milliwebers are in 1 microweber?
1 µWb = 0.001 mWb.
How do I convert microwebers to milliwebers?
Multiply the value in µWb by 0.001, or divide it by 1000. For example, 15 µWb × 0.001 = 0.015 mWb.
Is the µWb to mWb conversion exact?
Yes. Both units are defined exactly, and 1 µWb is exactly 0.001 mWb.
