Unit Converter

Use a unit converter for the specific gravity of stock-tank oil to convert between API, sp. gravity, and density in lb/ft3 or kg/m3.

Specific Gravity of Stock-Tank Oil

Copy

To convert from API gravity (°API) to specific gravity of oil or relative density with respect to water (sp. gr.), use this unit converter formula: 141.5 / (°API + 131.5) = sp. gr.

To convert from API gravity (°API) to density in pound per cubic foot (lb/ft3), use the formula: 141.5 / (°API + 131.5) × 62.3666 = lb/ft3

To convert from API gravity (°API) to density in kilogram per cubic meter (kg/m3), use the formula: (141.5 / (°API + 131.5)) × 999.01647 = kg/m3

To convert from oil specific gravity or relative density with respect to water (sp. gr.) to API gravity (°API), use this unit converter formula: (141.5 / sp. gr.) - 131.5 = °API

To convert from oil specific gravity or relative density with respect to water (sp. gr.) to density in pound per cubic foot (lb/ft3), use this unit converter formula: sp. gr. × 62.3666 = lb/ft3

To convert from oil specific gravity or relative density with respect to water (sp. gr.) to density in kilogram per cubic meter (kg/m3), use this unit converter formula: sp. gr. × 999.01647 = kg/m3

To convert from density in pound per cubic foot (lb/ft3) to API gravity (°API), use the formula: (141.5 × 62.3666 / lb/ft3) – 131.5 = °API

To convert from pound per cubic foot (lb/ft3) to specific gravity or relative density with respect to water (kg/m3), use the formula: lb/ft3 / 62.3666 = sp. gr.

To convert from density in pound per cubic foot (lb/ft3) to density in kilogram per cubic meter (kg/m3), use the formula: lb/ft3 × 16.01845 = kg/m3

To convert from density in kilogram per cubic meter (kg/m3) to API gravity (°API), use the formula: (141,360.83 / kg/m3) – 131.5 = °API

To convert from kilogram per cubic meter (kg/m3) to specific gravity or relative density with respect to water (sp. gr.), use the formula: kg/m3 / 999.01647 = sp. gr.

To convert from density in kilogram per cubic meter (kg/m3) to density in pound per cubic foot (lb/ft3), use the formula: kg/m3 × 0.062428 = lb/ft3
