Weber, ký hiệu Wb (phiên âm vêbê), là đơn vị đo từ thông Φ }} trong hệ SI, đặt tên theo nhà Vật lý Đức Wilhelm Eduard Weber.
Một weber là giá trị từ thông nếu nó giảm xuống 0 trong vòng 1 giây thì một vòng dẫn điện kín có diện tích mặt phẳng bên trong chắn được có độ lớn 1 mét vuông nhận được từ thông tối đa sẽ có suất điện động là 1 vôn.
