We need to write an original article for keyword "Lpm To M3 H". That likely means liters per minute to cubic meters per hour. Provide SEO-friendly HTML using only allowed tags: h2, h3, p, ul, ol, li, strong, em. No markdown fences, no other tags. Must be 600-900 words. Use natural headings. Use context when useful: references to unit conversion, tricks, etc. Provide article ready to be pasted directly. No intro, no conclusion? It says "Do not include intro, conclusion, or any kind of preamble." But we need headings. We can just start with

etc. But they said natural headings, so we can have headings as part of article. They want only safe HTML using h2, h3, p, ul, ol, li, strong, em. No other tags like div, etc. Also no markdown fences. So output should be raw HTML tags. We need 600-900 words. Let's aim around 700 words. Use paragraphs

. Use lists

  • . Use , . Use headings h2 and h3. We must not mention AI. Avoid unsupported claims. Provide factual conversion steps. Keyword "Lpm To M3 H" likely means "L per minute to m3 per hour". Provide conversion: 1 L/min = 0.06 m3/h? Let's calculate: 1 liter = 0.001 m3. So 1 L/min = 0.001 m3 per minute. Multiply by 60 minutes = 0.06 m3 per hour. Yes. So conversion factor 0.06. Conversely, to convert from m3/h to L/min multiply by (1/0.06)=16.666... So 1 m3/h = 16666.666... L/min? Wait 1 m3/h = (1/0.06) L/min = 16.666... L/min? Actually 1 m3 = 1000 L. So 1 m3/h = 1000 L per hour. Divide by 60 min = 16.6667 L/min. Yes. So conversion factor is 16.6667. We'll write article explaining concept, example, trick, etc. Use headings: maybe

    We need to keep within allowed tags. Use only h2, h3, p, ul, ol, li, strong, em. No other tags. Ensure no extra tags like strong only inside p? It's okay. Word count: need to count approximate words. Let's draft. I'll write paragraphs with about 100-150 words each. Let's approximate. Paragraph 1: maybe 120 words. Let's draft content. I'll write:
