Engineering Unit Converter
A fast, precision converter for construction professionals. Seamlessly translate values across Length, Mass, Pressure, Force, Volume, and more.
Why Unit Consistency Matters on Site
In the Nepali construction industry, a major source of errors occurs due to mixed unit systems. Architectural drawings are often dimensioned in the Imperial system (Feet and Inches), whereas structural engineering blueprints, survey data, and laboratory material tests strictly follow the Metric system (Meters, Millimeters, and Newtons).
Common Metric/Imperial Conversions
- 1 Inch (in) = 25.4 mm
- 1 Foot (ft) = 0.3048 m
- 1 Meter (m) = 3.2808 ft
- 1 Kilogram (kg) = 2.2046 lbs
Structural & Material Units
- 1 MPa (Pressure) = 1 N/mm²
- 1 Tonne (Mass) = 1,000 kg
- 1 Quintal = 100 kg
- 1 Cubic Meter (m³) = 35.3147 ft³ (cft)
Frequently Asked Questions
How many millimeters are in an inch?
There are exactly 25.4 millimeters (mm) in one inch. This conversion is crucial when reading structural drawings, as rebar diameters and cover blocks are always specified in mm, but masons often measure in inches.
How many kilograms are in a metric tonne?
There are 1,000 kilograms (kg) in one metric tonne. Heavy materials like steel reinforcement bars (rebar) and cement are usually billed in metric tonnes on large construction sites.
What is the difference between MPa and N/mm²?
There is no numerical difference. 1 Megapascal (MPa) is exactly equal to 1 Newton per square millimeter (N/mm²). Both are standard units used in structural engineering to denote the compressive strength of concrete (e.g., M20 grade concrete has a strength of 20 N/mm²).
