    数字平台规模(或称重秤orscales)是要测量的设备重量春季平衡orspring scales计算重量那是质量到重力的产物(9.807 m/s2)在弹簧上的力上,而使用平衡梁的平衡或一对比例可以通过平衡物体的质量与一个或多个已知质量的重量来比较质量。其中一些可以校准以用力(重量)单位读取纽顿instead of units of mass such as公斤。The balance or pair of scales using a traditional balance beam to compare masses may read correctly for mass even if moved to a place with a different non-zero gravitational field strength. Also the spring balances that are designed with reading of weight (force) in mind, would read correctly for weight in a different non-zero gravitational field strength.

    Scales and balances are widely used in commerce, as many products are sold and packaged by mass.

    Although records dating to the 1700s refer to spring scales for measuring mass, the earliest design for such a device dates to 1770 and credits Richard Salter, an early scale-maker.[[1这是给予的Spring scales came into wide usage in the United Kingdom after 1840 when R. W. Winfield developed the candlestick scale for weighing letters and packages, required after the introduction of the统一的便士邮政[2]邮政工人的弹簧尺度比平衡量表可以更快地工作,因为可以立即读取它们,并且不必与每个测量值仔细平衡。

    到1940年代,各种电子设备已连接到这些设计上,以使读数更准确。[[1这是给予的[3]负载电池,将压力(或力)转换为数字信号的小节点早在19世纪后期就开始起步,但是直到20世纪后期,它们才变得足够准确,可以广泛使用。[4]

    Mechanical scales[[编辑这是给予的

    机械刻度或平衡用于描述用于测量物体的质量,力量,张力和电阻而无需电源的称重装置。机械量表的类型包括弹簧秤,悬挂量表,三光束平衡和强制仪表。
