UNITS AND CONVERSION
Units are essential when describing real things.
Good engineering practice demands that each number should always be Accompanied with unit.
1 HOW TO USE UNITS
This table does not give an exhaustive list of conversion factors, but instead a minimal (but fairly compete) set is given. From the values below any conversion value can be derived. If you are not sure about this, ask the instructor to show you how.
A simple example of unit conversion is given below,
A simple unit conversion example:
HOW TO USE SI UNITS
1. Beware upper/lower case letter in many cases they can change meanings.
e.g.m =mili, mega
2. Try to move prefixes out of the denominator of the units.
e.g.N/cm or KN/m
3. Use slash or exponents.
e.g.(kg.m/s2)or (kg.m.s`2)
4. Use a dot in compound units.
e.g.N.m
5. Use spaces to divide digits when there are more than 5 figures, commas are avoided because their use is equivalent to decimal points in some cultures.
In some cases units are non-standard. There are two major variations US units are marked with �US� and Imperial units are marked with �IMP�.
