# 9 units of length equivalents in a fun online physics learning game.

 "Length Units" is a free online knowledge level game to sort the units of length (metre) by their equivalents. Minute to win it game. Physics learning game, suitable for online classes and interactive lessons. Fun physics educational game to explore and study the orders of length magnitude and the metric system of measurements of distance. Part of the Interactive Physics Workshop educational tools. Online physics educational game. Free online game for physics homework.

This physics class game include the following order of magnitude for units of length:
• femtometre (fm)
• picometre (pm)
• nanometre (nm)
• micrometre (µm)
• millimetre (mm)
• centimetre (cm)
• decimetre (dm)
• metre (m)
• decametre (dam)
• hectometre (hm)
• kilometre (km)

## How to play Length Units.

 There are 9 base units of length, marked by the multiples length symbol, situated on the left side of the screen. Drag and drop them in their correct equivalent value in the blank sockets of the green pyramid to the right of the screen. For example, go with the mouse over the round green circlet with 1cm. Click and hold the left mouse button and carry the circlet where 10 milimetres is. Sort all 9 units of length to win the game.

Knowledge Achievements:
Know 3 metre equivalents and get +1 Knowledge Level.
Difficulty: Hard.

### Class subject: Length Units.

 The length of an object is the distance between point A and point B. The basic length unit is the metre (m), using the The Metric System of Measurements of length. In geometric measurements, length is the most extended dimension of an object. In the International System of Quantities, length is any quantity with dimension distance. In other contexts, length is a measured dimension of an object. Length may be distinguished from height, which is vertical extent, and width or breadth, which are the distance from side to side, measuring across the object at right angles to the length. For example, it is possible to cut a length of wire shorter than the wire's width. In most systems of measurement, the unit of length is a base unit, from which other units are derived. Here are multiples of the length: 1 nanometre = 1000 picometres 1 micrometre = 1000 nanometres 1 millimetre = 1000 micrometres 1 centimetre = 10 millimetres 1 decimetre = 10 centimetres 1 metre = 10 decimetres 1 decametre = 10 metres 1 hectometre = 10 decametres 1 kilometre = 10 hectometres

This interactive lesson may answer the following questions:
• How many nanometres is one micrometre?
• How many millimetres is one centimetre?
• How many metres is one decametre?
• How many decametres is one hectometre?
• How many hectometres is one kilometre?
