One thousandth is to divide a number into 1000 parts, one of which accounts for one thousandth. The mathematical expression is 0.00 1.

We need to know what "one in a thousand" means. One thousandth is to divide 1 into 1000 parts, and the size of each part is11000, which is 0.00 1. So it can be concluded that one thousandth is 0.00 1.

Mathematically speaking, one thousandth can be expressed as a fraction of11000 or as a decimal of 0.005438+0. These mathematical expressions accurately describe the meaning and size of one thousandth.

We can also get one thousandth by calculation. For example, if we want to calculate one thousandth of 2, then we can divide 2 into 1000 parts, and the size of each part is 0.002. So one thousandth of 2 is 0.002.

We can draw the conclusion that one thousandth is 0.00 1. This is an accurate mathematical expression, which can be expressed in different mathematical forms such as fractions and decimals, and specific numerical values can be obtained through calculation.
