Understanding Centimeters and Inches
What is a Centimeter?
A centimeter (cm) is a unit of length in the metric system, used widely across the globe. There are 100 centimeters in a meter, making it a straightforward system based on powers of ten.
What is an Inch?
An inch is a unit of length from the imperial system, primarily used in the United States, Canada, and a few other countries. There are 12 inches in a foot, and unlike the metric system, it doesn’t work in neat decimal steps.
History Behind Both Units
The metric system dates back to the French Revolution, designed for simplicity and consistency. The imperial system, however, evolved over centuries through various British measurements and traditions.
The Metric vs. Imperial System
Origins of Each System
- Metric: Born in France, logical, decimal-based.
- Imperial: Rooted in British history, more traditional and less uniform.
Where Each System is Used Today
- Metric: Virtually every country except the U.S., Liberia, and Myanmar.
- Imperial: Mainly used in the United States.
Challenges of Switching Between Systems
Mixing the two can be a recipe for disaster. Imagine building a house where the measurements bounce between cm and inches—yikes!

5. How to measure my kitchen worktop?
To measure your kitchen worktop, whether it’s ceramic worktop, Dekton worktop, or Silestone worktop, follow these simple steps:
- Clear the area: Remove everything from your existing worktops to ensure accurate measurements.
- Measure length: Use a tape measure to get the total length of each worktop section along the back edge (the part against the wall).
- Measure depth: Measure from the front edge of the worktop to the wall.
- Note cutouts: Mark the positions and dimensions of any sink, hob, or other appliance cutouts.
- Consider overhangs: Account for any desired overhangs at the front or exposed edges.
- Measure for upstands/splashbacks: If you want these, measure the lengths and heights.
- Double-check: Always measure twice to ensure accuracy.
For custom materials like Dekton, Silestone, and ceramic worktops, it’s highly recommended to have a professional do a precise templating or site survey to ensure a perfect fit, as these materials often have specific requirements for cutouts, joints, and support.
