Meters. In collegiate and professional levels, all throws (including javelin) are measured in meters to abide by the universal measurement of the rest of the world. Official records for these events are in meters but can be converted to the nearest feet and inches.
It is measured in grams.

Just like any other substance in existence, the magnitude of sound or loudness can also be measured. In this case, the standard unit of measurement for loudness is called decibels.
You can convert one unit of measurement into another unit of measurement, such as kilograms to pounds, but you cannot convert a number into a unit of measurement, such as 110.00 to pounds. At least, not unless I want to guess what unit of measurement you are using (kilograms?).
That may refer to an object's mass (units: kilograms), to its momentum (measured in mass x velocity, units are kilogram x meter / second), or to its kinetic energy (measured in joules).
The measurement unit depends on the characteristic that is being measured.

measurement of volume.
It can be measured in any unit of measurement. *Edit: Remember that volume can be in any unit but it has to be cubed.
