Pound per cubic foot (lb/ft³) is the starting unit on this page for a density conversion.
Pound per cubic foot is part of the measurement language used in Pound per cubic foot appears in measurement references where lb/ft³ is the expected label.
lb/ft³ values are converted when working with values that are already written in lb/ft³ but the final answer needs to be shown in a different unit.
Kilogram per cubic meter (kg/m³) is the result unit produced by this lb/ft³ to kg/m³ conversion.
Kilogram per cubic meter remains common in Kilogram per cubic meter appears in measurement references where kg/m³ is the expected label.
kg/m³ results are useful for working with values that are already written in kg/m³, especially when converted densities are used in lab reports, material comparisons, fluid calculations, and engineering references.
Mathematically, kilogram per cubic meter (kg/m³) = pound per cubic foot (lb/ft³) converted with the formula below.
1 lb/ft³ = 16.018463 kg/m³
1 kg/m³ = 0.062428 lb/ft³
Formula: value × 16.018463374
Example: 15 lb/ft³ = 240.276951 kg/m³
Precision note: Keep enough decimal places to support your actual use. Keep both parts of the density unit together; converting only the mass or volume part will produce the wrong density.
1 lb/ft³ = 16.018463 kg/m³
1 kg/m³ = 0.062428 lb/ft³

Rounding depends on what the converted value is for. A casual estimate can be rounded for readability, while values used for fluid calculations and lab notes or material property tables may need more decimal places.
A common mistake is forgetting that 1 g/cm³, 1 g/mL, and 1000 kg/m³ describe the same density. For this pair, Keep the lb/ft³ label attached to the number so the value is not misread Keep the kg/m³ label attached to the number so the value is not misread
When reading the result in kg/m³, remember that keep the kg/m³ label attached to the number so the value is not misread. If another source gives a different kg/m³ value, compare the number of decimal places first. If the difference is large, check the starting value, selected units, and direction.
For this pair, use value × 16.018463374. A quick benchmark is 15 lb/ft³ = 240.276951 kg/m³, which can help you check whether the result is in the expected range.
It is the reverse direction. This page starts with lb/ft³ and returns kg/m³; the reverse starts with kg/m³ and returns lb/ft³.
Because Kilogram per cubic meter is the smaller unit in this pair, the converted number is larger than the starting lb/ft³ value. The relationship is 1 lb/ft³ = 16.018463 kg/m³.
