The number is read as Three hundred and ninety-three million, seventy-one thousand four hundred and twenty five.

Long scale and short scale for Large Numbers
There are two ways of saying big numbers Short scale and Long scale.
For whole numbers smaller than 1,000,000,000 (10^9 ), such as one thousand or one million, the two scales are identical. For larger numbers, starting with 10^ 9, the two systems differ. The long scale increases by powers of one million, whereas the short scale increases by powers of one thousand.
For example, In science and finance and in the USA a trillion is 1,000 billion, which is written as a one followed by 12 zeros. This is also called a short scale.
But there is also a long scale, which is used in France and was previously used in the United Kingdom, in which a trillion means 10 to the power 18 – thus, a million million million (tri- as in tricycle, tripod, triangle, etc.)
Often in Europe, you hear “Milliarde” in German, “miljard” in Dutch, “milyar” in Turkish and “миллиард” in Russian which are standard usage when discussing financial topics. The names ending in -illiard for numbers of the form 10^6n+3. Ex 10^9 is Milliard while 10^16 is Billiard
Due to its dominance in the financial world by the US dollar, short scale was adopted for official United Nations documents.
