Conversion of Units Often Used in Indonesia
| Conversion | Value |
|---|---|
| 1 hectare | 10,000 square meters |
| 1 are | 100 square meters |
| 1 kg of water | 1 liter (at room temperature) |
| 1 gram | 0.001 kg |
| 1 ppm | 1 mg/L or 1 g/m³ |
| 1 ppb | 0.001 mg/L or 1 µg/L |
| 1 m³ | 1,000 liters |
| 1 bar | 100,000 Pascal or ≈ 10 meters of water column |
| 1 µS/cm | ≈ 0.6-0.7 ppm TDS |
Brief Explanation
- 1 hectare and 1 are how many square meters?
- 1 kg how many liters?
- 1 gram how many kg?
- 1 ppm and 1 ppb how many grams?
- 1 m³ how many liters?
- 1 bar how many Pascals and meters of water column?
- Conductivity and TDS
1 hectare and 1 acre how many square meters?
- 1 hectare = 10,000 square meters
- 1 are = 100 square meters
Are is a unit of area often used in Bali and some other parts of Indonesia. 1 hectare equals 100 are.
Example:
- A 5 are plot of land = 500 square meters
- A rice field of 0.5 hectares = 5,000 square meters = 50 are
2. 1 kg how many liters?
For water at room temperature (about 25°C):
- 1 kg of water ≈ 1 liter
However, this is not true for all substances:
- 1 kg of coconut oil ≈ 1.07 liters
- 1 kg of palm oil ≈ 1.13 liters
- 1 kg of mercury ≈ 0.074 liters
1 gram how many kg?
1 gram = 0.001 kg = 1/1000 kg
General conversion:
- 1,000 grams = 1 kg
- 500 grams = 0.5 kg
- 250 grams = 0.25 kg
- 100 grams = 0.1 kg
4. 1 ppm and 1 ppb how many grams?
PPM (parts per million) and PPB (parts per billion) are units of concentration often used in water treatment.
For water:
- 1 ppm = 1 mg/L = 1 g/m³
- 1 ppb = 0.001 mg/L = 1 µg/L = 0.000001 g/m³
Example:
- Water with 5 ppm chlorine contains 5 mg chlorine per liter of water
- Water with 100 ppb arsenic contains 100 µg arsenic per liter of water
1 m³ how many liters?
1 m³ (cubic meter) = 1,000 liters
General conversion:
- 0.5 m³ = 500 liters
- 0.1 m³ = 100 liters
- 10 m³ = 10,000 liters
1 bar how many Pascals and meters of water column?
1 bar = 100,000 Pascals ≈ 10.2 meters of water column
Pressure is often used in water pumping and filtration systems:
- 1 atm (atmosphere) ≈ 1.01325 bar
- 1 bar ≈ 14.5 psi (pounds per square inch)
Conductivity and TDS
Electrical conductivity is often used to estimate the amount of total dissolved solids (TDS) in water:
1 µS/cm (microSiemens per centimeter) ≈ 0.6-0.7 ppm TDS
.
However, the exact conversion factor may vary depending on the ion composition of the water.
The Importance of Understanding Units in Water Treatment
Understanding these unit conversions is very important in the water treatment industry. Some applications include:
- Dosing of chemicals: Calculating the right amount of coagulant or disinfectant based on ppm.
- System design: Determining storage tank capacity in m³ or calculating pump pressure in bar.
- System design.
- Water quality analysis: Interpreting laboratory test results often using ppm or ppb.
- Water quality analysis.
- System efficiency: Calculating the flow rate in m³/hour or liters/minute.
- System efficiency.
At PT Watermart Perkasa, we use in-depth knowledge of these units to ensure accurate and efficient water treatment solutions for our customers across Indonesia.
