Length
• 1 kilometre (km) = 1000 metres (m)
• 1 metre (m) = 100 centimetres (cm)
• 1 centimetre = 10 millimetres (mm)
Measuring Length
• Metre stick/ruler (avoid the error of parallax) (nearest mm)
• Measuring Tape (nearest mm)
• Callipers (nearest mm)
• Vernier Callipers (nearest 0.1mm)
• Opisometer (nearest mm when used with metre stick/ruler)
• Trundle Wheel (nearest cm)
Mass
• The mass of an object is the amount of matter in it.
• Electronic balance is used to measure mass.
• 1 kilogram = 1000 grams
Time
• 60 seconds = 1 minute
• 60 minutes = 1 hour
• Watches / Clocks / Stopwatch / Electronic Timers
Temperature
• The temperature of an object is a measure of how hot or cold the object is.
• Measured in Degrees Celsius (°C) using a thermometer.
• Body temperature is 37°C.
• There are 4 types of thermometers: mercury/alcohol thermometers, thermoscan ear thermometer, electronic digital thermometers, temperature sensors.
