Unit FAQs
Why is Kelvin important in Physics?
Kelvin (K) is the SI unit for temperature because it starts at Absolute Zero (0 K), where molecular motion stops. Gas law formulas like PV=nRT strictly require temperature in Kelvin to work correctly.
How many Nanometers in a Meter?
There are 1 Billion (1,000,000,000) nanometers in a meter. Mathematically, 1 nm = 10-9 m. This scale is used in measuring light wavelengths and computer processors.
Difference between Mass and Weight?
Mass (measured in Kg) is the amount of matter in an object and remains constant. Weight (measured in Newtons or Lbs) is the force of gravity on that object, which changes if you go to the Moon or Mars.
