A petagram (Pg) is an SI-derived mass unit equal to 10^15 grams or one billion metric tonnes, used mainly in geosciences and climate science for extremely large masses.

How many kilotons are in one petagram?

One petagram equals one million metric kilotons (kt).

Can kiloton refer to energy units?

Yes, in the context of explosives or nuclear weapons, kiloton often refers to the equivalent energy in TNT, not mass.

What Is This Tool?

This online converter allows you to convert mass values from petagrams (Pg) to metric kilotons (kt). Petagrams represent extremely large masses often used in geosciences and climate science, while kilotons are useful for industrial, naval, and engineering mass measurements.

How to Use This Tool?

Enter the mass value in petagrams (Pg) you want to convert.
Select petagram as the input unit and metric kiloton as the output unit.
Click the convert button to view the result in kilotons (kt).

Key Features

Convert large-scale mass units between petagrams and metric kilotons with ease.
Browser-based tool requiring no downloads or installations.
Supports units commonly used in science, industry, and naval architecture.

Examples

2 Pg equals 2,000,000 kt
0.5 Pg equals 500,000 kt

Common Use Cases

Reporting large global carbon stocks or emissions in geosciences.
Quantifying industrial bulk shipments such as coal or ore.
Calculating displacement or capacity of large ships and submarines.
Assessing mass of icebergs, storage reservoirs, or small asteroids.

Tips & Best Practices

Always verify the context to avoid confusion with kiloton energy units used in explosives.
Ensure you are using metric tons for consistent conversions.
Provide additional context when interpreting large mass values after conversion.

Limitations

Kiloton unit may be confused with energy units such as TNT equivalent in explosives contexts.
Conversions assume metric ton units; non-metric tons will lead to inaccuracies.
Very large masses in petagrams may require more context after being converted to kilotons.
