What is a unit converter and why is it important in Physics and Chemistry?
A unit converter is a tool (manual or digital) that helps convert one measurement unit into another (e.g., meters to kilometers). It is essential because in the Pakistani education system, Physics and Chemistry problems often require converting values to SI units before solving numericals.
Which unit system is used in Pakistani schools for Physics and Chemistry?
Most textbooks (Matric & Intermediate) follow the SI system (International System of Units), but older systems like CGS (centimeter-gram-second) or FPS (foot-pound-second) are sometimes mentioned for conceptual clarity.
Why do we need to convert units in Physics and Chemistry?
To maintain consistency (all calculations should be in the same system).
To avoid mistakes in formulas (since formulas usually work only in SI units).
To compare experimental values with standard results.
What are the basic SI units for length, mass, time, and temperature?
Length → meter (m)
Mass (Weight in Physics) → kilogram (kg)
Time → second (s)
Temperature → Kelvin (K)
(In Chemistry, °C is commonly used, but it is often converted to K in formulas.)
What are common unit conversions for length in Pakistani Physics exams?
1 km = 1000 m
1 m = 100 cm
1 cm = 10 mm
1 inch = 2.54 cm
1 foot = 12 inches
What are common unit conversions for weight/mass?
1 kg = 1000 g
1 g = 1000 mg
1 tonne = 1000 kg
1 lb (pound) ≈ 0.4536 kg
