What it does

RapidTables groups mathematical, electrical, grade, time and financial calculations with unit conversions and other web utilities.

RapidTables separates math, grades, electrical calculations and reference tools. In its grade calculator, choose percentage, letter or points input and enter each assessment's grade and weight; extra rows and zero-to-two decimal result places are available. The guide distinguishes percentage weights from point/hour weights, which divide the weighted sum by total weight. The additional-grade target option explicitly assumes percentages. A separate final-exam section takes current grade, desired course grade and exam weight to report the required exam result. Match the course's actual grading/letter-conversion rules before interpreting the estimate.
