About 247QuickTools

247QuickTools is a free collection of online tools — unit converters, text utilities, colour tools, calculators, date tools and more. Everything runs in your browser. No account and no sign-up. What you type into a tool is processed on your device and is not uploaded to us.

What you will find here

The site has around 285 interactive tools (text, numbers, dates and times, colour, generators, writing, education, events, business and everyday-life calculators), more than 1,300 individual unit converters grouped into 21 categories, almost 200 side-by-side comparison pages, 47 buying and how-to guides, and a set of “days until” countdowns for UK dates and events. You can browse all of them from the home page.

How the numbers are worked out

Every converter shows its formula and a worked example, so you can check the result by hand. Length, mass and volume factors come from the international definitions (for example, the inch is exactly 2.54 cm and the pound exactly 0.45359237 kg). Temperature conversions use the standard Celsius, Fahrenheit and Kelvin formulae. The UK money tools (income tax and National Insurance, stamp duty, payroll, pensions and student loans) use the published GOV.UK rates and thresholds for the 2026-27 tax year, and are labelled with the year they apply to. They are estimates for planning, not a substitute for official calculators or professional advice.

Keeping pages up to date

Pages that depend on rates, thresholds or dates are reviewed when the published figures change and at the start of each tax year. Tool pages are tested with known answers, and where a figure cannot be verified against a primary source we would rather leave it out than guess.

Privacy

Tools run in your browser and nothing you enter is sent to our servers. We use Google Analytics to see which pages are useful, but only after you accept cookies; if you decline, analytics stay off. Our privacy policy has the details.

Who builds this

247QuickTools is built and maintained by a UK-based qualified primary school teacher and FA Level 2 football coach. Tools are checked for accuracy against published reference data — ISO standards, official conversion factors, government tax bands and similar primary sources.

What we believe about tools

A tool is only useful if it works correctly, loads quickly and doesn't ask you to do anything before you can use it. Every page on 247QuickTools is built to that standard: the tool works immediately, with no pop-ups and no requirement to create an account.

Affiliate disclosure

Some pages include links to products on Amazon. 247QuickTools participates in the Amazon Associates programme across the UK, US, EU and 10 other regional storefronts. As an Amazon Associate we earn a small commission from qualifying purchases. This does not affect the price you pay, and affiliate links are never placed inside tool functionality — only in optional buying guide sections.

247QuickTools also works with the CJ Affiliate (Commission Junction) network to recommend software we think is genuinely useful alongside our tools — for example password managers, VPNs and website/PC security products. As with Amazon, we may earn a small commission if you buy through these links, at no extra cost to you, and they are only ever placed in clearly labelled recommendation sections, never inside the tools themselves.
