英錢(英語:pennyweight,縮寫:dwt),或譯為本尼威特便士重,英美重量單位,等於24格令120金衡盎司1240金衡磅,約等於0.054857常衡盎司[1]或1.55517384 [2]


在中世紀,一個英國便士英語Penny (British pre-decimal coin)的重量是相差無幾的,在貨幣方面,1便士等於120盎司或1240標準純銀英語sterling silver磅。當時所用的磅是塔磅。中世紀的英國便士等於32塔衡格令(也稱麥格令)。1527年,金衡制代替塔衡制,在金衡制中,舊的塔衡磅等於5400金衡格令(也稱巴利肯/大麥粒),塔衡英錢為2212金衡格令,約等於1.46克。1527年後,英錢改用金衡制英錢。[3]


在1878年的《重量及計量條例英語Weights and Measures Act》中,金衡磅和英錢已失去了在英國的法定單位地位;僅金衡盎司及其十進制輔助單位仍具法定地位。金衡盎司在英國享有特殊的免除米制化英語Metrication的法律地位。[4]

Applied to nails, such adjectives denote the original price (in 15th c.) per hundred; as fivepenny nail, a nail which cost 5d. a hundred, tenpenny nail, a nail costing 10d. a hundred.
