Base Quantities

1. Length (m) - Area (m2) , Volume (cm3 )2. Mass (kg) - Weight (N)3. Temperature (K) 4. Time (s)5. Electric Current (A)

Length (m, cm, mm, km)

- Straight (ruler, measuring tape)- Curve (thread and ruler / opisometer dan ruler)- Diameter ( internal caliper / external caliper / vernier caliper / micrometer screw gauge)

Area (m2, cm2, mm2, km2, Hectare)

- Regular (Graph / Formula)- Irregular (Graph)

Volume (m3, cm3, mm3, mℓ, ℓ)

- Regular (Water Displacement Method / Formula)(Measuring Cylinder / Eureka Can)

- Irregular (Water Displacement Method / Formula)

Mass (kg, g, tonne, mg)

- Quantities of matter- Not affected by gravity (does not change).- Chemical Balance, Beam Balance, Lever Balance.

Weight (N)

- Pull of gravitational force- Changes from place to place- Spring Balance, Compression Balance

Temperature (K, °C, °F)

- Laboratory Thermometer(-10°C to 110°C, no rat / constriction, big range, less sensitive or accurate)

- Clinical Thermometer (35°C to 42°C, has rat / constriction, small range, more sensitive or accurate)
