Linear Meters to kg/t Converter
Calculate the weight of steel rebar, pipes, and profiles from length. Includes ISO/ASTM standard database for accurate metal trading and engineering estimates.
About
Professional estimation in metal trading and construction logistics requires precise weight calculations based on profile geometry. Buying steel by length while paying by weight creates a discrepancy that demands accurate conversion factors. This tool utilizes standard specific weights for ferrous and non-ferrous metals to determine total mass from linear dimensions. Engineers and procurement officers use this data to verify supplier invoices and calculate transport loads.
The calculation relies on the theoretical nominal mass per meter defined in ISO and ASTM standards. Actual weight may vary slightly due to manufacturing tolerances (rolling margins). For critical structural applications, verifying the specific density of the alloy is recommended.
Formulas
The core principle involves multiplying the total length by the specific linear density of the selected profile. The formula is:
Where:
- M = Total Mass (kg)
- L = Total Length (m)
- wspec = Specific Weight (kg/m)
