Hydrogen is typically measured in several units depending on the context. In chemistry, it is often quantified in moles (mol), which represents the amount of substance. For gaseous hydrogen, it can also be measured in liters (L) at a given temperature and pressure, or in grams when discussing mass. Additionally, in the context of energy production, hydrogen is sometimes measured in joules or kilowatt-hours (kWh).
SI unit or Newton
Powder is measured in Ounce (OZ). In India however it is often measured in Grams.
Enthalpy is the measurement of heat, Joule (J) is the unit. Temperature is not a measurement of heat. Temperature has the unit Kelvin (K) or Celsius (oC)
Magnetic flux density is measured in tesla.Magnetic flux is measured in weber.
Plasma volume is typically measured in milliliters (ml) or liters (L).
The measurement unit depends on the characteristic that is being measured.

measurement of volume.
Decibel is a measurement of loudness.
Microns, this is measured with a micrometer
It can be measured in any unit of measurement. *Edit: Remember that volume can be in any unit but it has to be cubed.
Probably the pound.
