In view of the widespread difficulties being encountered in introducing the kilopascal for blood pressure measurements, the 1981 World Health Assembly endorsed an earlier recommendation for a gradual change to the SI unit, but recommended that both the millimetre of mercury and the kilopascal be used simultaneously in the interim. A new name, "the sievert" (Sv), for the SI unit of dose equivalent (ionizing radiation), and other changes related to the "litre", the "candela", and the "radian" and "steradian" are reported.
鉴于在引入千帕斯卡进行血压测量时普遍遇到困难，1981年世界卫生大会认可了一项早期建议，即逐步改用国际单位制单位，但建议在此过渡期间同时使用毫米汞柱和千帕斯卡。报告了剂量当量（电离辐射）的国际单位制单位的一个新名称“希沃特”（Sv），以及与“升”、“坎德拉”、“弧度”和“球面度”相关的其他变化。
