Here are some key notes on measurements for Maths Literacy:

  • What is Measurement? Measurement is the process of assigning a numerical value to a physical quantity, like length, mass, or time, using standard units. It helps us quantify and compare things in the real world.

  • Units of Measurement & Conversions Different quantities have different units. For length, we use millimeters (mm), centimeters (cm), meters (m), and kilometers (km). For mass, we use grams (g) and kilograms (kg). For capacity (volume of liquids), we use milliliters (ml) and liters (L). Time is measured in seconds, minutes, hours, and days. It's crucial to know how to convert between these units (e.g., 1 m=100 cm1 \text{ m} = 100 \text{ cm}, 1 kg=1000 g1 \text{ kg} = 1000 \text{ g}, 1 L=1000 ml1 \text{ L} = 1000 \text{ ml}).

  • Perimeter The perimeter is the total distance around the outside edge of a 2D shape. It's like walking along the boundary of a field.

    • Rectangle: P=2(l+w)P = 2(l + w)
    • Square: P=4sP = 4s
    • Circle (Circumference): C=2πrC = 2\pi r or C=πdC = \pi d
  • Area The area is the amount of surface a 2D shape covers. It's measured in square units (e.g., cm2\text{cm}^2, m2\text{m}^2).

    • Rectangle: A=l×wA = l \times w
    • Square: A=s2A = s^2
    • Triangle: A=12×b×hA = \frac{1}{2} \times b \times h
    • Circle: A=πr2A = \pi r^2
  • Volume The volume is the amount of space a 3D object occupies. It's measured in cubic units (e.g., cm3\text{cm}^3, m3\text{m}^3).

    • Rectangular Prism: V=l×w×hV = l \times w \times h
    • Cylinder: V=πr2hV = \pi r^2 h
  • Rate A rate compares two different quantities with different units, often involving time. Examples include speed (distance per time, e.g., km/h) and fuel consumption (distance per volume, e.g., km/L).
