KG to Liters Using Specific Gravity

How KG to Liters Using Specific Gravity Works?

KG to Liters Using Specific Gravity works by multiplying the specific gravity (SG) by the density of water at the reference temperature, then dividing the mass in kilograms (kg) by that density. The reference water density is 0.99997 kg/L at 4 °C (39.2 °F), 0.99904 kg/L at 15.56 °C (60 °F), 0.99821 kg/L at 20 °C (68 °F) or 0.99705 kg/L at 25 °C (77 °F).

4 steps to use KG to Liters Using Specific Gravity

1. Choose the direction: "kg → Liters" or "Liters → kg".
2. Enter the specific gravity (SG) from the data sheet, hydrometer or certificate of analysis.
3. Select the water reference temperature: 4 °C, 15.56 °C (60 °F), 20 °C or 25 °C.
4. Enter the weight in kilograms (kg) and read the volume in liters (L).

KG to Liters Using Specific Gravity Formula

The KG to Liters Using Specific Gravity formula is liters = kilograms ÷ (SG × ρwater), written as V = m ÷ (SG × ρw). The formula has 4 variables:

• V (volume) is the result in liters (L).
• m (mass) is the weight in kilograms (kg).
• SG (specific gravity) is the density ratio of the liquid to water, with no unit.
• ρw (water density) is the water density at the reference temperature in kg/L.

3 worked examples of the KG to Liters Using Specific Gravity formula

1. 1 kg at SG 0.832 (60 °F): 1 ÷ (0.832 × 0.99904) = 1.203 L.
2. 25 kg at SG 1.25 (20 °C): 25 ÷ (1.25 × 0.99821) = 20.04 L.
3. 200 kg at SG 0.88 (60 °F): 200 ÷ (0.88 × 0.99904) = 227.49 L.

The API gravity formula converts petroleum SG to degrees API: API = 141.5 ÷ SG − 131.5. SG 0.832 equals 38.6 °API.

KG to Liters Using Specific Gravity Conversion Table

The KG to Liters Using Specific Gravity conversion table lists the SG at 60 °F (15.56 °C) and the liters in 1 kg, 25 kg and 200 kg for 9 common liquids.

What Is KG to Liters Using Specific Gravity?

KG to Liters Using Specific Gravity is a mass-to-volume conversion that uses the specific gravity (SG) of a liquid in place of its density.

Specific gravity (SG, relative density) is the density of a liquid divided by the density of water at a stated temperature. SG has no unit, and an SG of 1.000 means the liquid weighs the same as water.

• A liquid with an SG below 1 floats on water, and 1 kg fills more than 1 L.
• A liquid with an SG above 1 sinks in water, and 1 kg fills less than 1 L.
• Petroleum products report SG at 60 °F (15.56 °C) under ASTM D1298 and ASTM D4052.

What Are the Uses of KG to Liters Using Specific Gravity?

There are 4 main uses of KG to Liters Using Specific Gravity: petroleum loading, chemical dosing, brewing and battery maintenance.

• Petroleum loading: Terminals convert tonnes of crude oil to barrels with the SG from the bill of lading.
• Chemical dosing: Plants convert kilograms of acid to liters with the SG on the certificate of analysis.
• Brewing: Brewers read SG with a hydrometer to track sugar: an original gravity of 1.050 means 1 L of wort weighs 1.050 kg.
• Battery maintenance: Lead-acid battery electrolyte reads SG 1.265 at full charge, and 1 kg of electrolyte fills 0.79 L.
