==定義==
1韋伯為一匝線圈其[[磁通量]]在1秒內均勻遞減至零而產生1[[伏特]][[電動勢]]之磁通量。<ref>{{Cite web|title=法定度量衡單位及其所用之倍數、分數之名稱、定義及代號修正規定|url=https://www.bsmi.gov.tw/wSite/public/Data/f1564459299996.pdf|accessdate=|author=|date=|format=|publisher=|language=|archive-date=2020-01-14|archive-url=https://web.archive.org/web/20200114052908/https://www.bsmi.gov.tw/wSite/public/Data/f1564459299996.pdf|dead-url=yes}}</ref> <ref>{{cite web

韦伯可以用不同單位的乘積來表示
:<math>\mathrm{Wb} 
=\dfrac{\mathrm{kg} \cdot \mathrm{m}^2}{\mathrm{s}^2 \cdot \mathrm{A}}
=\mathrm{V} \cdot \mathrm{s} 
=\mathrm{H} \cdot \mathrm{A} 
=\mathrm{T} \cdot \mathrm{m}^2 
=\dfrac{\mathrm{J}}{\mathrm{A}}
=\dfrac{\mathrm{J} \cdot \mathrm{s}}{\mathrm{Q}}
=10^8\mathrm{Mx}
</math>

其中
Wb = 韦伯,
<br>V = [[伏特]],
<br>T = [[特斯拉 (单位)|特斯拉]],
<br>J = [[焦耳]],
<br>m = [[公尺]],
<br>s = [[秒]],
<br>A = [[安培]],
<br>Q = [[庫倫]],
<br>H = [[亨利 (单位)|亨利]],
<br>Mx = [[馬克士威 (單位)|馬克士威]].
