Conversion FAQ

When weighing produce it's common to want to know answers to the following questions. Using the conversion tools at the top of this page will yield answers to these questions. But, should you want to calculate manually, here is the info you need.

How many grams are in a pound (lb)?

This is a common cooking question as people want to be able to convert from pounds to grams. There are 453.59237 grams in a pound (lb). So, multiply your pound figure by 453.59237 to get your grams figure (or 454 for a rough conversion).

Mass or weight?

A few people have written to me asking why I state that units such as grams, pounds and ounces are units of mass and not weight. If you're unsure about why they are units of mass, please see this article: what is the difference between mass and weight?
