But I didn't. [Chorus] Oh I, I'd done a lot of things different. [Verse 2] I wished I'd a spent more time with my dad when he was alive. Now I don't have the chance. I wish I had told my brother how much I loved him before he went off to war.

What does ppm mean? This is an abbreviation for parts per million and it also can be expressed as milligrams per liter (mg/L). This measurement is the mass of a chemical or contaminate per unit volume of water. Seeing ppm or mg/L on a lab report means the same thing. One ppm is equivalent to the absolute fractional amount multiplied by one million. A better way to think of ppm is to visualize putting four drops of ink in a 55-gallon barrel of water and mixing it thoroughly.
