Frequently Asked Questions
How much is 690 µg/L in ppm?
690 µg/L equals 0.69 ppm for water (density ≈ 1 kg/L).
How do I convert 690 µg/L to ppm?
For water: 690 ÷ 1,000 = 0.69 ppm. General: ppm = µg/L ÷ (density × 1,000).
Is µg/L the same as ppb?
For water: yes, 1 µg/L = 1 ppb. Both represent the same concentration. µg/L is mass/volume (preferred in labs), ppb is dimensionless.
