As a way of measuring mass, distance, and volume, the metric uses decimals. Though Simon Stevin, a Flemish mathematician, first suggested such a device in his 1586 book De Thiende (The Tenth), centuries before the metric system became a common measure of measurement.

The following base units are used in the metric system: The following base units are used in the metric system: The following base units are used in the metric system:

- easures length in meters
- Kilogram – measures mass – measures mass
- Liter – Liter – measures volume – measures literacy – measures volume

These units are broken down by the strength of ten, as well as the terms used for smaller and larger units carry across the base units. For example, a kilo is equal to the factor of 1000, and deci is equal to the factor of 0.1. A kilometer, kilogram, and kiloliter will all be 1,000 of each base unit, while decimeter, decigram, and deciliter all translate to 0.1 of the base unit. This standardization allows for fast conversions.

Celsius is the other metric unit of measure used in the United States. This unit, also known as centigrade, measures temperature. Water boiling and freezing points are 100 degrees different. Although Fahrenheit marks the freezing point of water at -32°F, Celsius marks it at 0°C.

## U.S. weights and measurements are included in the table below

In 1988, the metric system in the United States became the preferred method for weights and measures in trade in the United States. However, the metric system also works with the Imperial system of measurements. Miles, not kilometers, are used to determine distances. nces in recipes are measured in cups and ounces. Football measures distance by the yard. And yet, our physicians and mechanics depend on the metric system to function. We also buy bottles of soda and water by liter measurements. Among other occupations that mainly use the metric system are::::: Those are examples of other occupations that use the metric system.

- Manufacturing
- Pharmacy
- Transportation
- Energy
- Healthcare
- Technology
- Restaurants

## The national metric day in the United States has a long tradition

The National Council of Teachers of Mathematics, 1977, declared the week of May 9-13 as National Metric Week. The council postponed the observance of the metric system until the week of October 10th to remind the metric system's usefulness. On October 10th of this week, the National Metric Day takes place.
