IMPORTANT CONVERSIONS |
| PRESSURE | | ENERGY |
1) | 1 Kg/Cm2 | = | 14.223 psig | | 1) | kcal/hr x 3.968 | = | BTU/hr |
2) | 1 Bar | = | 14.504 psig | 2) | Ton | = | ( Watts/hr x 3.413 ) / 12000 |
3) | 1 Bar | = | 1.0197 Kg/cm2 | 3) | Watts/hr | = | (No.of Tons x 12000 ) / 3.413 |
| | | |
| VOLUME | 4) | BTU/hr | = | Watts/hr x 3.413 |
1) | 1 Ft3 | = | 28.3 Litree | 5) | 1 Ton | = | 12000 btu/hr |
2) | 1 Metre3 | = | 35.315 Ft | 6) | kchl/hr | = | Watts/hr x 0.8598 |
3) | 1 oz | = | 29.57 milliliter | 7) | 1 HP | = | 760 Watts |
4) | 1 Metre3 | = | 1000 Litres | 8) | 1 KW | = | 1000 Watts |
| 9) | 1 Ton | = | 3.413kw |
10) | 1 Ton | = | 3024 kcal/hr |
| | | |
| TEMPERATURE | | AREA |
1) | 0F | = | 1.8 x 0C+32 | | 1) | 1 metre2 | = | 35.315 ft2 |
2) | 0C | = | ( F-32 ) / 1.8 | | |
| | | | | | | | |
| WEIGHT | | DISTANCE |
1) | 1 Ton | = | 1000 Kg | | 1) | 1 INCH | = | 25.4 MM |
2) | 1 Kg | = | 2.2 Pounds | 2) | 1 Feet | = | 12 Inches |
| | | | 3) | 1 Meter | = | 3.28 foot |
| | | | 4) | 1 Meter | = | 39.36 inch |
