API To Density Converter
A 30 degree API crude has a specific gravity of about 0.876, or roughly 875 kg/m3. Quick answer: Add 131.5 to the API gravity, then divide 141.5 by the result. For example, 10 API is 1 SG, 30 API is 0.8762 SG and 40 API is 0.8251 SG. The API to density formula Specific gravity…
