Converting units in Belgium
Belgium uses legal measurement units based on the International System of Units. Imperial values still appear in imported products, automotive data, construction references, aviation, recipes and online shops.
SI and legal units as the base
FPS Economy describes national standards as supporting traceability to the International System of Units. Belgium's legal units are set through the Economic Law Code and the 2020 royal decree updating legal measurement units.
Common Belgian conversions
- Inches to centimetres for screens, pipes, bicycle parts, tyres, tools and fittings.
- Feet to metres for imported plans, product manuals, aviation or real-estate references.
- Pounds to kilograms for shipping, fitness equipment, parcels and online purchases.
- Horsepower to kW for vehicle ads, workshop records and technical specifications.
When precision matters
Rounded values are enough for rough comparisons. Keep more digits for healthcare, dosing, construction, machining, verified instruments, product labels, loads, fasteners and contractual measurements.
