How do you convert specific gravity to API?

How to estimate API gravity?

1. Divide 141.5 by the specific gravity of the liquid.
2. Subtract 131.5 from the resultant to obtain the API gravity.

What is the relationship between density specific gravity and API?

API gravity is another expression of this measurement that uses the Density/Specific gravity for its conversion. The higher the api the less dense the sample is. For example at 60°F: an api of 10.0 is equal to 1.0000 g/cm3. While an api of 80.0 is equal to 0.6684 g/cm3.

How is SG calculated from API?

The formula for API gravity is API = (141.5/SG) -131.5 where SG is the specific gravity of the petroleum liquid being measured. For example, for an API gravity of 50, add 131.5 to obtain 181.5. Divide 141.5 by (131.5 + API gravity) to obtain the specific gravity of the oil.

How do you convert specific gravity?

Specific gravity is a ratio of the density of a substance to the density of a reference substance, usually water. Since the density of water is one gram per cubic centimeter, you calculate specific gravity by dividing the density of a substance by one gram per cubic centimeter.

How do you convert density to API?

The formula can be reversed to find the density of the petroleum liquid. Add 131.5 to the API gravity. The formula for API gravity is API = (141.5/SG) -131.5 where SG is the specific gravity of the petroleum liquid being measured. For example, for an API gravity of 50, add 131.5 to obtain 181.5.

How do you convert density to specific gravity?

How do you convert gravity to specific gravity?

For example, the specific gravity of 0.84 corresponds to the density of 840 (0.84 x 1000) kg/cubic meters. Multiply the density by the acceleration of gravity (9.81) to calculate the specific weight. In our example, the specific weight is 840 x 9.81 = 8,240.4.

What is the formula for adding SG to API gravity?

Add 131.5 to the API gravity. The formula for API gravity is API = (141.5/SG) -131.5 where SG is the specific gravity of the petroleum liquid being measured.

What is specific gravity (SG)?

API to SG Calculator The American Petroleum Institute established API gravity as a measure of the density of petroleum liquids relative to water. The greater the API, the less dense the liquid. Our float switch product line lists the specific gravity (SG) which the device will be able to float.

What is the measurement unit of g/cc?

Measurement unit: g/cc Full name: gram/cubic centimetre Plural form: grams/cubic centimeter

What is API to specific gravity?

Online API to Specific Gravity calculator. API gravity express the gravity or density of crude oil and liquid petroleum products. API is devised jointly by the American Petroleum Institute and the NIST – National Institute of Standards and Technology. The measuring scale is calibrated in terms of degrees API.
