I build, test and maintain every calculator on MeasuredBuild.

I’ve spent 5 years building online tools and calculators. I care about one thing: an answer you can rely on the first time. I also hold an MBA, which shapes how I plan, measure and improve every tool.

What I’ve built

50 calculators and tools over 5 years.

Every tool on MeasuredBuild, from the formula to the finished page.

How every tool is built

• Checked against hand-worked answers. I work out each formula by hand and test the tool against those answers. The concrete calculator passes more than 100 of these checks.
• Compared with trusted calculators. Every tool’s results are compared with well-known calculators before it goes live.
• Figures straight from the manufacturer. Numbers like how much concrete one bag makes come from the manufacturer’s own data sheet, linked on the page.
• Clear about rounding and waste. When a tool rounds up or adds a waste allowance, the page shows how much.

Always up to date

• I review figures whenever a manufacturer updates its data sheet.
• Each tool shows the date it was last checked.
• Every update is noted on the tool’s page with its date.

Smart tools, personally checked

I use AI tools to work faster on text and code. I personally check every number, formula and sentence before it goes live.
