The metric system is only used in Bulgaria in the building and allied trades. The measurements are normally given in metres, centimetres and millimetres for measurments and in kilogram and tonnes for weights. These measures are inconveniet if you are used to to the Imperial unit system. For our clients from UK we have put together these conversion tables wich hopefully will help you to calculate the building measurments in the system you know better
Length Conversion
| Imperial/USA unit | Metric (SI) unit | Metric (SI) unit | Imperial/USA unit | |
| 1 Inch | 2.54 centimeters | 1 Centimeter | 0.39 inches | |
| 1 Foot | 30.48 centimeters | 1 Meter | 3.28 feet | |
| 1 Yard | 0.91 meters | 1 Meter | 1.09 yards | |
| 1 Mile | 1.61 kilometers | 1 Kilometer | 0.62 miles |

Temperature Conversion (°C / °F)
- The freezing point of water in Fahrenheit is 32 degrees, in Celsius it is 0 degrees.
- The boiling point of water in Fahrenheit is 212 degrees, in Celsius it is 100 degrees.
- Consequently the difference between freezing and boiling is 180 degrees Fahrenheit (212-32) or 100 degrees Celsius (100-0). This means that 180 degrees change in Fahrenheit is equal to 100 degree change in Celsius, or more simply 1.8 degrees Fahrenheit equals 1.0 degrees Celsius.
This gives rise to the following equations to convert between Celsius and Fahrenheit:
- °C = (°F – 32) ÷ 1.8
For example: (68°F-32) ÷ 1.8 = (36) ÷ 1.8 = 20°C - °F = (°C x 1.8) + 32
For example: (20°C x 1.8) + 32 = (36) + 32 = 68°F
Some common examples for Celsius and Fahrenheit comparison:
- Freezing = 0 °C , 32°F
- Room temperature = 20 °C , 68°F
- Normal body temperature = 37 °C , 98.6°F
- A very hot day = 40 °C , 104°F
- Boiling point of water = 100 °C , 212°F
