You can see that this sort of calculation is going to take us into small mass units indeed.

But there is power in Ashton's use of mass units.

When the French invented the metric system in the late 1700s, they also used an amount to define their mass unit.

We first need the energy equivalent of one atomic mass unit:

The unified atomic mass unit and the dalton are different names for the same thing.

Liquid flow measurements are usually in volumetric or mass unit.

The mass of the neutron is also about one atomic mass unit.

The application must be submitted in mass units.

The mass unit may relate to dry matter or to the mass of carbon generated.

See the article on the history of the modern unified atomic mass unit for the resolution of these problems in 1961.

It serves to define the atomic mass unit and is, by definition, equal to 1 u.

Thus the molecular mass of each member differs by 14 atomic mass units.

GHG emission estimates should be reported in common mass units.

The atomic mass unit is convenient for expressing the masses of atoms and molecules.

While dimensional mass units may be used, the comments about integers are then no longer applicable.

Atomic mass unit, used to express atomic and molecular masses.

For a mass increase to be measurable, the change of energy per mass unit must be enormously large.

No specifications exist for the conversion of volume units to weight or mass units.

Monoisotopic mass is typically expressed in unified atomic mass units.

Many antibacterial compounds are relatively small molecules with a molecular weight of less than 2000 atomic mass units.

The unified atomic mass unit u was defined as:

Mass accuracy is usually measured in ppm or milli mass units.

The Dalton (Da) is another name for the unified atomic mass unit.

The measured ratios are offset from their absolute values almost entirely by a fractionation component of about 0.16% per mass unit.

The oil table is presented in mass units (tonnes) to facilitate comparison with other energy resources and the incorporation of natural gas liquids.
