__HERE ARE THE BASICS FOR YOUR TEST__

=Units = This section has information on the system of units used by us. We use the Systéme Internationale (SI) for units of physical quantities. This international system of units is based on the following five units:
 * 1) metre
 * 2) kilogram
 * 3) second
 * 4) ampere
 * 5) kelvin

Other SI units are defined in terms of these basic units. SQA has published a list of the physical quantities in Higher Physics, together with the symbol and SI unit of each quantity - click on the link to see the list. Learn these quantities, symbols and units a few at a time so that by the time you sit your Higher you will know all of them. You also need to know the following prefixes:

Table of units
Each prefix can go before any SI unit. For example:
 * G || Giga || 109 || one thousand million ||
 * M || Mega || 106 || one million ||
 * k || kilo || 103 || one thousand ||
 * m || milli || 10-3 || one thousandth ||
 * µ || mu || 10-6 || one millionth ||
 * n || nano || 10-9 || one thousandth of a millionth ||
 * p || pico || 10-12 || one millionth of a millionth ||

Table of units
When you are trying numerical problems always make sure that you use the SI unit of each quantity given - this guarantees that the quantity you are calculating will be in its SI unit. <span style="background-color: #fbf49c; color: #db5902; display: block; font-family: verdana,helvetica,arial,sans-serif; font-size: 13.2px;"> The kilogram is the SI unit for mass - do not change kilograms to grams.
 * 1 pF || =1 picofarad= || 1 × 10-12 farads || = 1 × 10-12 F ||
 * 1 ns || =1 nanosecond= || 1 × 10-9 seconds || = 1 × 10-9 s ||
 * 1 µm || =1 micrometre= || 1 × 10-6 metres || = 1 × 10-6 m ||
 * 1 mA || =1 milliamp= || 1 × 10-3 amps || = 1 × 10-3 A ||
 * 1 kV || =1 kilovolt= || 1 × 103 volts || = 1 × 103 V ||
 * 1 MJ || =1 megajoule= || 1 × 106 joules || = 1 x 106 J ||
 * 1 GHz || =1 gigahertz= || 1 × 109 hertz || = 1 × 109 Hz ||

Remember that a) to multiply two powers of ten you add the powers b) to divide two powers of ten you subtract the powers.
