To convert proton masses to kg: multiply by 1.67262192369 × 10⁻²⁷.
mp ≈ 1,836 × mₑ ≈ 1.00728 u. About 0.1% heavier than a neutron.
For example, 1 Proton Mass (mp) = 1.672622e-23 Decigram (dg).

The proton mass is the rest mass of a proton, approximately 1.673 × 10⁻²⁷ kilograms or about 938.3 MeV/c².
mp ≈ 1,836 × mₑ ≈ 1.00728 u. About 0.1% heavier than a neutron.
To convert proton masses to kg: multiply by 1.67262192369 × 10⁻²⁷.
Nuclear energy calculations, radiation therapy dosimetry, and proton beam therapy for cancer.
A proton's mass is mostly from the kinetic energy of quarks and gluons (via E=mc²), not from the quark masses themselves (~1%).
Assuming quarks make up most of the proton's mass — quarks contribute only ~1%. The rest is binding energy.
The proton:electron mass ratio (1,836:1) is a fundamental number in physics. It determines atomic structure.
The decigram is a unit of mass equal to one tenth of a gram (10⁻¹ g) or 100 milligrams.
1 dg = 0.1 g = 100 mg = 10 cg.
To convert dg to grams: divide by 10. To convert dg to mg: multiply by 100.
Limited modern use. May appear in some European cooking recipes or educational worksheets.
The decigram was in wider use in the 19th century when the metric system was still establishing conventions.
Confusing dg (decigram) with dag (dekagram) — they differ by a factor of 100.
Deci = one-tenth, deka = ten. They are opposite: dg = 0.1 g, dag = 10 g.
