The International System of Units In 1960, the units of the metric system was streamlined by an international conference. The conference created a system of units called the Systeme Internationale d’Unites, abbreviated as SI.
7 base units Physical Quantity 1. Mass 2. Length 3. Time 4. Amount of substance 5. Temperature 6. Electric current 7. Luminous intensity Unit and symbol 1. Kilogram, Kg 2. Meter, m 3. Second, s 4. Mole, mol 5. Kelvin, K 6. Ampere, A 7. candela, cd
Derived units/Compound unit Physical Quantity Unit and symbol area square meter, m 2 volume cubic meter, m3 pressure Pascal, Pa
Common Prefixes used in the metric system for big numbers Kilo- k thousand 1000 Mega- M million 1,000,000 Giga- G billion 1,000,000,000
Common Prefixes used in the metric system for small numbers deci- d tenth 0.1 centi- c hundredth 0.01 milli- m thousandth 0.001 micro- µ millionth 0.000 001 nano- n billionth 0.000 000 001

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
