Ø6 Rebar — Weight, Area & Ordering Numbers
Ribbed reinforcing bar B500 per EN 10080 / DIN 488
Ø6 rebar weighs 0.222 kg per meter — the nominal value every supplier and engineer uses, from the 28.3 mm² nominal cross-section at 7,850 kg/m³ (ribs are already accounted for: the nominal diameter is defined so that mass, not outside size, matches). A standard 12 m mill bar weighs 2.66 kg, so one tonne is about 375 bars or 4,505 meters.
These numbers are what you need to turn a cutting list in meters into an order in kilograms — and to check a delivery note against what actually arrived on the truck.

Frequently Asked Questions
How much does 6 mm rebar weigh per meter?
0.222 kg per meter (nominal, B500 per EN 10080). The quick site formula is d²/162: 6² / 162 ≈ 0.222 kg/m.
How many Ø6 bars are in a tonne?
About 375 bars of 12 m (2.66 kg each), or 750 bars of 6 m. One tonne of Ø6 is roughly 4,505 meters of bar.
What is the cross-section area of Ø6 rebar?
28.3 mm² nominal — the value used in reinforcement schedules. For example, 5 bars of Ø6 give 142 mm² of steel.
What is the US equivalent of Ø6 rebar?
The closest US bar is #3 (9.53 mm, 0.56 kg/m). US sizes are numbered in eighths of an inch, so exact matches are rare — check the required steel area, not just the diameter.
