Engineering
Concrete Mix Design Calculator
Estimates the total cement mass required for a concrete pour based on volume and target strength. Use it when specifying mix proportions for slabs, columns, or foundations to meet structural and durability requirements.

Engineering
Power Transmission Calculator
Converts torque (N·m) and rotational speed (rpm) into mechanical power in kilowatts. Use it when sizing motors, drives, or shafts, or when checking whether a drivetrain can handle a given load without overheating.
