How to Make an SI Units Map

Three steps to a study map of the SI base units, built from your material.

  1. 1

    Add your material

    Upload your notes or type the topic, such as SI base units.

  2. 2

    AI builds the map

    The map groups each base unit with its quantity and symbol.

  3. 3

    Study, expand, export

    Expand branches, quiz yourself, or export the map as PNG or PDF.

Understanding the SI Base Units Map

The International System of Units (SI) defines seven base units from which all other metric units are derived. Each base unit measures one independent physical quantity: length, mass, time, electric current, thermodynamic temperature, amount of substance, and luminous intensity. A mind map of these units shows each quantity as a branch, with the unit name and symbol on a child node.

  • Length: metre (m), the unit of distance
  • Mass: kilogram (kg), the only base unit with a prefix
  • Time: second (s), the unit of duration
  • Electric current: ampere (A), the unit of current flow
  • Temperature: kelvin (K), measured from absolute zero
  • Amount and light: mole (mol) and candela (cd)

Use the map to revise the seven units, their symbols, and the quantities they measure. To build a version from your own course notes, create a personalized map with CogniGuide.

SI Base Units Questions

Common questions about the seven base units and making a map of them.

How many SI base units are there?

There are seven SI base units: the metre, kilogram, second, ampere, kelvin, mole, and candela. Each measures one independent quantity, and all other SI units are built from them.

Why is the kilogram a base unit with a prefix?

The kilogram is the only SI base unit whose name includes a prefix, kilo. It is defined as the base unit of mass, and the gram is derived from it by dividing by a thousand.

Can I make an SI base units map from my own notes?

Yes. Upload a PDF, Word file, or slides, or type the topic, and CogniGuide's AI builds a mind map you can expand and edit.

Is it free to create a units map with CogniGuide?

There is a free plan that allows 5 creations a week with no payment needed. Paid plans raise those limits.
