Study Notes

Measurement Systems

  • Measurement determines length, mass, capacity, temperature, and time.
  • The Standard International (SI) system is used globally.
  • Older systems, like British (e.g., mile, yard) and Indian (e.g., Tola, Masha) ones, also still exist.
  • The metric system combines prefixes (like kilo, hecto, deca, deci, centi, milli) with base units (like metre, litre, and gram).
  • Two main measurement systems: Metric and Standard International (SI). SI is widely used, Metric was used earlier.

Length Measurement

  • Length is the distance between two points.
  • Units include metre (m), centimetre (cm), millimetre (mm), decametre, hectometre, decimetre, mile, yard, foot, and inch.
  • Conversion factors exist: 1 metre = 100 centimetres; 1 mile = 1609.344 metres; 1 yard = 0.9144 m; 1 yard = 3 feet; 1 foot = 12 inches; 1 inch = 2.54 cm; 1 mile = 1760 yards
  • Tools for measuring length are rulers, metre scales, measuring tapes, etc.; length, width, height, and thickness can be measured using a ruler.
  • Mile and yard are British units.
  • A metric chart exists for length measurements with prefixes (kilo, hecto, deca, deci, centi, milli) relating to powers of 10.
  • The base unit of length is the metre (m).
  • Base unit prefixes illustrated: kilo, hecto, deca, metre, deci, centi, milli
  • Numerical values for each unit in metric chart.
  • Length can also be measured in decametre, hectometre, and decimetre.

Mass Measurement

  • Mass is the amount of matter in an object.
  • The SI unit is the kilogram (kg).
  • Smaller units are grams (g) and milligrams (mg).
  • Larger units include kilograms (kg) and tonnes (1000 kg); Quintal (100 kg).
  • Conversion factors exist for converting between units (e.g., 1 milligram = 0.1 centigram).
  • Historical Indian units like Tola, Masha, and Ratti existed
  • Larger units can be converted into smaller units by multiplying or dividing, using metric chart prefixes.
  • Conversion examples: 1 milligram = 1/10 centigram and other related conversions in the metric system.
  • Mass indicates how light or heavy an object is. Heavier objects generally have more mass.

Capacity/Volume Measurement

  • Volume is the space a 3D object occupies; capacity is the volume for liquids or gases.
  • The SI unit is the litre (L).
  • Smaller units are millilitres (mL). Larger units are kilolitres (kL) and megalitres (ML).
  • Volume is calculated by multiplying length, width, and height.
  • A metric chart exists for capacity/volume measurements mirroring the length and mass prefixes
  • Volume measurement is also needed to find capacity for liquids or gases.
  • Conversion examples: 1 mega litre (ML) = 1000 kilolitre (kL); 1 litre (L) = 1000 millilitre (mL); 1 kilolitre (kL) = 1000 litre (L)
  • Volume is the space a 3D object occupies; capacity is the amount a container can hold.

Time Measurement

  • Time measures duration.
  • The SI unit is the second (s).
  • Other units include minutes, hours, days, weeks, months, and years.
  • Conversions exist: 1 year ≈ 365 days; 1 month = 30–31 days; 1 week = 7 days; 1 day = 24 hours; 1 hour = 60 minutes; 1 minute = 60 seconds
  • Time zones exist due to Earth's rotation.
  • Leap years occur every 4 years.
  • Extremely long distances can be measured in light-years (light travels in one year).
  • Different time zones exist globally with varying abbreviations (e.g., IST for India Standard Time; GMT for Greenwich Mean Time; PST for Pacific Standard Time).
  • Examples of time zone abbreviations and their respective countries/regions

Temperature Measurement

  • Temperature measures hotness or coldness.
  • Units include Celsius (°C), Fahrenheit (°F), and Kelvin (K).
  • Instruments include clinical, laboratory, and weather thermometers.
  • Normal human body temperature is 37°C or 98.6°F.
  • Conversion formulas exist.
  • Celsius, previously known as Centigrade, is named after Anders Celsius; Fahrenheit after Daniel Gabriel Fahrenheit.
  • Conversion formulas for Celsius, Kelvin, and Fahrenheit exist.
  • Conversion formulas provided including Celsius to Kelvin, Kelvin to Celsius, Fahrenheit to Celsius, and Celsius to Fahrenheit.
  • Temperature is a measure of hotness or coldness.
  • Different temperature scales exist.
  • Specific scales are used for different contexts. Clinical thermometer example.

Unit Conversion

  • Conversion factors facilitate changing between units.
  • Metric charts for different measurements exist using prefixes and their corresponding power of 10.
  • Conversion tables and formulas are available for converting between units.
  • Example conversions shown (e.g., 1 mile = 1760 yards)
  • Unit conversions are essential for interchanging between different measurements.
