Part-per Trillion [ppt] to Part-per Billion [ppb] Converter

Quick Reference

1 Part-per Trillion (ppt) = 0.001 Part-per Billion (ppb)

1 Part-per Billion (ppb) = 1000 Part-per Trillion (ppt)

How to Convert Part-per Trillion to Part-per Billion

1 ppt = 0.001 ppb
1 ppb = 1000 ppt

To convert Part-per Trillion to Part-per Billion, divide the value by 1000 (equivalently, multiply by 0.001). To convert Part-per Billion back to Part-per Trillion, multiply by 1000.

Example: convert 10 ppt to ppb:
10 ppt = 10 x 0.001 = 0.01 ppb

↔ Convert Part-per Billion to Part-per Trillion

Part-per Trillion

Definition: Part-per trillion (ppt) is a unit used to express extremely low concentrations, representing one part of a substance per trillion parts of the mixture. It is often used in environmental science, toxicology, and chemistry to quantify trace amounts of pollutants or contaminants.

History/origin: The concept of 'parts per' notation originated from the need to express very small concentrations or proportions. 'Part per trillion' is a logical extension of 'parts per million' (ppm) and 'parts per billion' (ppb), becoming relevant with advancements in analytical techniques that allowed for the detection of increasingly smaller quantities.

Current use: PPT is commonly used to measure trace contaminants in water, air, and soil. It is also used in pharmaceutical analysis to quantify impurities, and in forensic science to detect trace amounts of substances in samples. Regulatory agencies often use ppt to set permissible levels for pollutants.

Part-per Billion

Definition: Parts per billion (ppb) is a way of expressing extremely dilute concentrations of substances. It represents the number of parts of a substance per billion parts of the mixture.

History/origin: Similar to ppm, ppb was developed to express even smaller concentrations than ppm. It's a natural extension of the parts-per notation system.

Current use: PPB is used when measuring extremely low levels of contaminants or trace elements, for example, in sensitive environmental monitoring or in advanced chemical analysis.

Part-per Trillion [ppt] to Part-per Billion [ppb] Converter

What is 1 ppt in ppb?
1 Part-per Trillion (ppt) equals 0.001 ppb, and 1 ppb equals 1,000 ppt.
How do I convert Part-per Trillion to Part-per Billion?
Divide by 1,000: 10 ppt ÷ 1,000 = 0.01 ppb. The converter above does it for any value, with the precision you choose.
What is 100 ppt in ppb?
100 ppt = 0.1 ppb. Common amounts are listed on this page, each with its own step-by-step page.
Is a Part-per Trillion bigger than a Part-per Billion?
No. 1 ppt is only 0.001 ppb: it takes 1,000 ppt to make 1 ppb.
