在水文资料整編中常常要把分鐘化成小时,如果一个个地去算,非常麻煩且浪費时間,现提出用表查算的方法,不但可提高工作效率,且可保証成果的精度。此表仅制到30分鐘,如30分以上可采用累加法查算,例如35分鐘因30分=0.5小时5分=0.083小时则35=0.5+0.083=0.583小时。 In hydrological data reorganization, minutes are usually converted into hours. If one by one, it is very troublesome and time-consuming, a table-based calculation method is proposed, which can not only improve work efficiency but also ensure the accuracy of the results. This table is only made to 30 minutes, such as more than 30 minutes can be calculated using the cumulative method, such as 35 minutes because of 30 minutes = 0.5 hours 5 minutes = 0.083 hours then 35 = 0.5 +0.08 = 0.583 hours.
