1 microgram (µg) = 1 x 10 -6 grams (g) |
1 gallon (gal) 美國加侖 = 3.7854118 Liters (L) 英國加侖 --> 升 × 4.55 imperial gallons to liters × 4.55 |
1 milligram (mg) = 0.001 grams (g) |
1 µg/mL = 1 part per million (ppm) = 1 µg/g* |
1 kilogram (kg) = 1000 grams (g) = 2.205 lbs. |
1 µg/L = 1 part per billion (ppb) |
1 pound (lb) = 453.59237 grams (g) |
1 mg/mL = 1000 ppm = 1 mg/g* |
1 milliliter (mL) = 0.001 Liters (L) |
1 mg/L = 1 ppm = 1000 ppb |
1 Liter (L) = 1000 milliliters (mL) |
1 ppb = 0.001 ppm = 1000 ppt |
1 Liter (L) = 0.26417205 gallons (gal) |
1 ppt = 0.001 ppb = 1 x 10 -6 ppm |
