- 1Standardan exact quantity that people use for comparison.
- 2SI SystemThe system used by scientists around the world to make measurements.
- 3LengthLength is a measure of how long an object is or the distance between two points. Unit meter or m
- 4MassA measure of how much matter is in an object.
Unit= kilogram or kg - 5VolumeThe amount of space the object takes up.
Unit=Liter or L - 6Timeinterval between two events. Unit = seconds = s
- 7TemperatureMeasure of heat in an object. Unit = Kelvin = K
The metric system uses Celsius (C) The U.S. uses Fahrenheit (F) - 8Temperature ConversionsK = °C + 273 °C = 5/9 (°F - 32)
°F = (°C * 9/5) + 32 - 9Mega Prefix and Units(M) 100000 (Hint 6)
