How to convert gram square centimeters to pound square feet
These units describe mass moment of inertia (mass times distance squared). Second moment of area uses length to the fourth power and belongs to a different quantity.
Use x for the value in g·cm², b for the intermediate value in kg·m², and y for the result in lb·ft².
lb·ft² = g·cm² × 1e-7 ÷ 0.042140110093804806
Worked examples
10 g·cm² ≈ 0.0000237303604042 lb·ft²
Step 1: (10 × 1e-7) ≈ 0.000001 kg·m².
Step 2: 0.000001 ÷ 0.0421401100938 ≈ 0.0000237303604042 lb·ft².20 g·cm² ≈ 0.0000474607208085 lb·ft²
Step 1: (20 × 1e-7) ≈ 0.000002 kg·m².
Step 2: 0.000002 ÷ 0.0421401100938 ≈ 0.0000474607208085 lb·ft².
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
About Gram square centimeters
Gram square centimeters (g·cm²) measures moment of inertia under the conventions above. The base value in kg·m² is (x × 1e-7), where x is the numerical value in g·cm². Factors shown here are rounded for display; calculations use the stored factor.
About Pound square feet
Pound square feet (lb·ft²) measures moment of inertia under the conventions above. The base value in kg·m² is (x × 0.0421401100938), where x is the numerical value in lb·ft². Factors shown here are rounded for display; calculations use the stored factor.
