×1000

The mathematical expression ×1000 represents multiplication by one thousand. When a number is multiplied by 1000, its value increases by a factor of one thousand. This operation is commonly used in various fields, including science, engineering, and finance, to scale quantities. For instance, in measurement conversions, multiplying a value in meters by 1000 would express it in millimeters. Similarly, in scientific notation, a number like 3.4 × 10^3 is equivalent to 3.4 × 1000. Multiplying by 1000 effectively shifts the decimal point three places to the right. For whole numbers, this is equivalent to adding three zeros to the end of the number. For example, 5 × 1000 equals 5000. In scientific contexts, the prefix "kilo" often denotes multiplication by 1000, as seen in kilometers (km) which are 1000 meters, or kilograms (kg) which are 1000 grams. The operation is a fundamental aspect of arithmetic and is essential for understanding numerical relationships and transformations.
