UK Paper Stock to US Conversion: A Comprehensive Guide

Are you planning to import paper products from the UK to the US but finding it challenging to understand the differences in paper stock standards? You're not alone. The transition between UK and US paper stock can be quite complex, but with the right knowledge, you can ensure a seamless conversion. This guide will help you navigate through the nuances of UK paper stock and convert them effectively for use in the US.

Understanding UK Paper Stock

The first step in converting UK paper stock to US standards is to understand the key differences. In the UK, paper stock is often measured in grams per square meter (gsm), also known as grams per square centimeter (gsm). On the other hand, the US commonly uses pounds (lb) to measure paper weight.

UK GSM to US Pound Conversion

To convert UK paper stock to US pounds, you can use the following formula:

1 pound = 0.44 lbs (rounded down) 1 gsm = 0.066 lbs

For example, if you have a paper stock of 100 gsm in the UK, you can convert it to US pounds as follows:

100 gsm * 0.066 lbs/gsm = 6.6 lbs

This means that 100 gsm UK paper is equivalent to 6.6 lbs US paper.

Converting Paper Thickness and Basis Weight

When converting paper stock, it's also important to consider the thickness and basis weight. In the UK, the basis weight is the weight of 500 sheets of paper (1 ream) of a given thickness and size. In the US, the basis weight is the weight of 500 sheets of a given thickness and size.

To convert the UK basis weight to the US basis weight, you can use the following formula:

1 lb US = 500 sheets 1 gsm UK = 1 sheet

For example, if you have a paper stock with a UK basis weight of 100 gsm, it would be equivalent to 500 gsm in the US.

Here are some common UK paper stocks and their US equivalents:

• 80 gsm UK = 6.6 lbs US
• 100 gsm UK = 8.3 lbs US
