1, the weight factor of the math book

Math books usually have more pages, and the more pages, the greater the weight of the paper. The quality of paper will also affect the weight of books, and high-quality paper is usually heavier. Cover and binding methods will also increase the weight of books. Hard cover and hardcover books are heavier, while soft cover and paperback books are lighter.

2. Average weight of math books

The weight of math books is between several hundred grams and several kilograms. Specifically, an ordinary mathematics textbook for primary and secondary schools may weigh about 500 grams to 1 kg. And large textbooks, reference books or professional mathematics works may be heavier, generally more than 2 kg.

3. The actual situation of math books

In fact, the weight of each math book may be different, depending on the publishing house, version, binding method and other factors. Therefore, to accurately understand the weight of a specific math book, it is best to check the detailed information of the book or directly weigh it.

The weight difference of math books and the characteristics of e-books

I. Textbooks, math books

Teaching materials for students: Teaching materials for students are usually thin and light, weighing between several hundred grams and several kilograms.

Teaching materials for teachers: Teachers' teaching materials are usually richer in content and heavier in weight, which may exceed 1kg.

Second, the weight difference between reference books and research works.

Reference books: Reference books are generally heavy, maybe more than a few kilograms.

Research works: Research works are usually huge academic works, which may weigh more than several kilograms.

Third, the characteristics of e-books

With the development of science and technology, more and more math books appear in the form of e-books. The weight of e-books depends on the size of digital files, while reading these books on electronic devices does not need to consider the physical weight.
