韦伯是国际单位制中磁通量的单位[1]，缩写Wb，是以德国物理学家威廉·韦伯的名字命名的。
1Wb = 1V·s = 108 Mx （馬克士威）

韦伯可以用法拉第电磁感应定律来推导，即平均每秒一個韦伯的變化可以產生一伏特的電動勢[2]。
韦伯可以用不同單位的乘積來表示
- Wb=kg⋅m2s2⋅A=V⋅s=H⋅A=T⋅m2=JA=108Mxdisplaystyle mathrm Wb =dfrac mathrm kg cdot mathrm m ^2mathrm s ^2cdot mathrm A =mathrm V cdot mathrm s =mathrm H cdot mathrm A =mathrm T cdot mathrm m ^2=dfrac mathrm J mathrm A =10^8mathrm Mx
其中
Wb = 韦伯,
V = 伏特,
T = 特斯拉,
J = 焦耳,
m = 公尺,
s = 秒,
A = 安培,
H = 亨利,
Mx = 馬克士威.
