Why use Fortitude21’s technical calculators?

Because each one shows its working. The jerry can calculator runs on the Sphere Handbook water rates and labels every planning margin as one you can change. The spill pallet calculator applies the rule where the store is, cites the law, code or guidance behind it and says which of the three it is. The decoder reads a mark in the order the UN Model Regulations set.

And because the answer turns into a specification. Every result names the products in our range that meet it, so a figure becomes a quotation request with the quantities already in it. Each tool page also carries its method, worked examples and sources in plain text, so you can check a figure before you rely on it.

We make jerry cans and liquid containers to order and quote against a drawing. See how on our About Us page, or go to the range:

Every tool here also answers as JSON, free and with no key. See the dangerous goods and packaging API.
