Answer 1

In our daily lives, we use several physical quantities to measure different aspects of our surroundings. Below is a list of some commonly used physical quantities, their standard units, and the devices used for their measurement.

Physical Quantity	Unit	Measuring Device	Usage
Length (Distance)	Meter (m)	Scale, Vernier caliper, Odometer	Measuring height, width, or distance
Mass (Weight)	Kilogram (Kg)	Beam balance, Electronic balance	Weighing groceries, gold, medicines
Time	Second (s)	Clock, Stopwatch, Atomic clock	Measuring time duration
Temperature	Kelvin (K) or Celsius (°C)	Thermometer, Pyrometer	Checking body temperature, weather
Electric Current	Ampere (A)	Ammeter, Multimeter	Measuring electricity in circuits
Light Intensity	Candela (cd)	Photometer, Lux meter	Measuring brightness of lights
Force	Newton (N)	Spring balance, Dynamometer	Measuring push or pull on objects
Pressure	Pascal (Pa)	Barometer, Manometer	Measuring air or liquid Pressure

In daily life, we rely on various measuring devices to ensure accuracy in tasks like shopping, cooking, construction, and science. Using standard measurement units helps maintain consistency and reliability in different fields.
