In body copy spell out numbers from one to ten, then use numerals. Spell out all numbers at start of sentence (Forty-eight people were injured...) In headings, though, numerals are fine for everything. For thousands and millions upwards: 3,000, 500,000, 2 million, 8 billion... abbreviate in headings to 2b, 8m with discretion.
