How to say "hundreds" in Japanese

• 何百なんびゃくCommon
  nounCovers 'hundreds' as an unspecified, unknown amount: like other 何- words it can ask 'how many hundreds?', and in statements it leaves the figure vague, suggesting a large indefinite number.
  何百なんびゃく羽わとキジを撃うった。↗

  We shot pheasants by the hundred.
• 数百すうひゃくCommon
  nounThe word for a rough estimate: 'several hundred' presents the figure as approximately known rather than unknown, and its 'hundreds (of)' sense fits plain descriptive statements about quantity.
  ちなみに、ウチのクリニックから数百すうひゃくメートルの近場ちかばに「ランプ」が建設けんせつ中ちゅうです。↗

  Incidentally a motorway ramp is being constructed in the neighbourhood, a few hundred metres away, of my clinic.

Choose 数百 to state a rough estimate of several hundred; choose 何百 when the number is unknown or deliberately vague, including questions, though both can render an indefinite 'hundreds'.
