What is a hundredweight (US)?

A hundredweight (US) is a unit of mass equal to 100 avoirdupois pounds or exactly 45.359237 kilograms, commonly used in bulk goods trading.

What is a petagram (Pg)?

A petagram is an SI-derived mass unit equal to 10^15 grams or one billion metric tonnes, often used in geosciences and climate science.

Why convert from hundredweight to petagram?

To translate mid-scale commercial weights into very large mass scales used in scientific research, facilitating analysis of global-scale inventories like carbon stocks or ice mass changes.

Common Use Cases

Pricing and trading bulk agricultural products using hundredweight (US)
Calculating freight or packaging weights for commodities
Expressing large-scale scientific mass measurements for global carbon stocks or ice-sheet changes
Converting mid-scale commercial weights to very large scale masses for research purposes

Tips & Best Practices

Use this conversion to relate commercial bulk weights to global mass quantities in scientific fields
Be aware that resulting petagram values will be very small for typical hundredweight amounts
Ensure conversions serve meaningful comparison scales rather than everyday weight checks

Limitations

Petagram units express extremely large masses, so converted values are often tiny decimals
Small numeric results may not be practical for routine commercial weight usage
Some precision or rounding issues can arise with very small numbers relative to petagrams
Suitable context is needed to make this conversion meaningful
