Is it true that financial accounting is for external users and management accounting is for internal users ?

I THINK IT IS A GOOD QUESTION THE FINANCIAL ACCOUNTING IS THE MOTHER OF ACCOUNTING SCIENCE SO IT IS FOR INTERNAL AND EXTERNAL USERS BUT THE MANAGEMENT ACCOUNTING IS FOR INTERNAL USERS

Financial accounting is for both internal and external users.But,Management accounting is for internal users only.

Partially true. Financial Accounting is used by both insiders and outsiders..but Management Accounting is used by insiders only.

the answer is correct financial information is used mostly by external users and when preparing financial accounts you need to follow rules and regulation for eg (ifrs) Whereas you can prepare management accounts without following any specified format because it is the internal documents

yes,

Managerial accounting is used primarily by those within a company or organization. Reports can be generated for any period of time such as daily, weekly or monthly. Reports are considered to be "future looking" and have forecasting value to those within the company.

Financial accounting is used primarily by those outside of a company or organization. Financial reports are usually created for a set period of time, such as a fiscal year or period. Financial reports are historically factual and have predictive value to those who wish to make financial decisions or investments in a company.

I dont think it is. I see that both are for internal users. External users will need a bit of both.

Yes,usually  it thinks like this

but not necessarily that management accounting is only for internal use, there are so many information which are helpful for the business understanding comes from the managements accounts. 

There is no legal requirement for an organization to use management accounting, but publicly traded firms (limited companies or whose shares are bought and sold on an open market) must, by law, prepare financial account statements

IFRS financial statements are used by all stakeholders, being shareholders, government agencies, employees, suppliers and customers, financial institutions.

The management accounts are used by internal users, management to provide a basis of analysis of costs, direct cost variations, costs verses budgets.
