$1 a . m . u . = 1.6726219 \times 10^{- 27} k g$ $1 a.m.u.=1.6726219xx10^(-27) kg$ .

Explanation:

1 atomic mass unit (a.m.u.) is the mass of a proton or a neutron which is equal to $1.6726219 \times 10^{- 27} k g$ $1.6726219xx10^(-27) kg$ .

The mass of a Hydrogen atom is 1 a.m.u. But, also we can say that the molar mass of a hydrogen is equal to $1 \frac{g}{mol}$ $1g/"mol"$ and this is because:

$1.6726219 \times 10^{- 24} g \times 6.022 \times 10^{23} = 1.007 g/mol$ $1.6726219xx10^(-24) gxx6.022xx10^(23)=1.007"g/mol"$

which is close to the mass that you find in a periodic table.
