NIST SP 1247 SI Base Units Relationships Poster – a colorful poster illustrating the relationships of the International System of Units (SI) derived units with special names and symbols and the seven traditional base units.

The Last Artifact documentary and companion Grade 5 to 12 educational resources, which document the work that went on behind the scenes to modernize the International System of Units (SI).

The changes became effective on World Metrology Day, May 20, 2019.

Redefining the SI – In November 2018, the world’s measurement experts voted and unanimously approved a revision of the SI that establishes a measurement system entirely based on physical constants of nature.

Here h W is the physical quantity, its value expressed in the unit "meter," unit symbol m, is 169 m, and its numerical value when expressed in meters is 169.

Example: the value of the height h W of the Washington Monument is h W = 169 m.

Thus, the numerical value of a particular physical quantity depends on the unit in which it is expressed.

The value of a physical quantity is the quantitative expression of a particular physical quantity as the product of a number and a unit, the number being its numerical value.

A unit is a particular physical quantity, defined and adopted by convention, with which other particular quantities of the same kind are compared to express their value.

A physical quantity is a quantity that can be used in the mathematical equations of science and technology.

Examples are the mass of the moon and the electric charge of the proton.

A quantity in the particular sense is a quantifiable or assignable property ascribed to a particular phenomenon, body, or substance.

The difference between 1,000,000 and 10,000,000 as written is only one zero, but in number terms the difference is nine million. Unless you have a good understanding of mathematics and the exponential number system, any number above a couple of thousand quickly gets meaningless. Given this background, is it any wonder that most people find it hard to grasp the enormously large and incredibly small numbers that we come across in modern life. It certainly makes accounting super simple. Instead, they rely on a word for "a few" and a word meaning "a lot". In fact, there are some languages that don't have a number system. There was no evolutionary pressure for humans to know the exact number of these large quantities of things. When the number of things does get large, we just use words like "forest" for thousands of trees or "flock" for thousands of birds. The couple of hundred people in a settlement, or a thousand animals on the land. Now, let’s get to converting!įor most of human history, we have only been used to quite small numbers.
