Molecular Weight Calculator 对比 Flange Hole Marker 的使用情况和统计数据
The Molecular Weight Calculator is a physics/math tool designed to find the average molecular weight (MW) of molecules by inputting their chemical formulas.
Features:
- Instant calculation
- Results can be copied to other apps
- Includes formula references
- Supports up to 16 decimal places
Note: Chemical formulas are case-sensitive (e.g., C22H30N4O).
Definitions:
- Molecular mass (molecular weight): The mass of one molecule of a substance, expressed in unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
- Molar mass (molar weight): The mass of one mole of a substance, expressed in grams per mole (g/mol).

This app is very useful during hole center Marking on flange at a given Pitch Circle Diameter.
This app gives hows much cord length required to divide required No of hole on our available Pitch Circle Diameter.
This app is very useful for those who are dealing with flange hole marking or bolt hole marking on flanges or any other application where we had to divide required no of parts on pitch circle diameter.
This app is for professional and any other who are working in the field of fabrication of process equipment such as pressure vessel, heat ex changer, storage tank,reactor, agitator or mixer and heavy engineering Equipment.
In this app Inputs required only pitch circle diameter ( PCD )or bolt hole circle diameter ( BCD ).
key words : Bolt Hole Diameter,Pitch circle Diameter,flanges, hole marking, fabrication, pressure vessel, welding etc
