I built a firewood calculator cordage, cu/ft, weight, BTU, and more

[Nord]

Hi all,

I started working on a website for the firewood business myself and my sons decided to start. I got sucked into building a firewood calculator which at first was just a simple cu/ft and cordage type calculator. But somehow ended up going far past that.

Posting it here as I figure some here might find it useful, feedback is welcome, I hope you guys like it!

Note: Results in Heating Energy and Weight are dynamic and affected by whether you choose wet or dry for "Wood Condition".

Thank you

Make it in normal - metric .

did urma chuck stool just swear? I'm ok with feet and inches or metric, UK child of the seventies... we had to learn a whole barrel of er.. stuff

Make it in normal - metric .

Not sure how normal it is, I know very few people who use it up here in the great white north.

But I am sure I can add a measurement type toggle

Sooo I got the multiple wood types completed today, mixed load calculations now possible!

You can select up to 4 "WoodTypes" and set a % for each (must equal 100%). Weight and BTU totals will be affected by this change.



I have not forgot about adding metric, it is coming

Ohhh, adding the measurements fathom, league and toise would be great too!!

The calculator has been used 500 times in the last 24 hours, great to see!

Few more things incoming:

- Option to use it in "stack" mode or pile mode for loose piles.
- Switch between metric and imperial
- Some more wood types to add
- In stack mode options to set number of rows and gap size.
- Option to set wood stove / burner efficiency %.

Any way you could add a preemptive field/calculator to generate a Cord Quantity amount from starting with inputs of log length & diameter? I'm sure there's other calculators to derive this separately...I just thought "one stop shopping" with yours might be kinda nice ... happy chainsawing and Merry Christmas from Leduc, AB

I have started working on a wood volume calculator which can do this. It will be able to calculate volume of a single tree or many. I am making it seperate from the firewood calculator because I don't want the firewood calculator becoming too busy, it also requires a pretty good chunk of code and the firewood calculator page is already getting pretty big, even with moving much of the data and functions into its own API / database on another server.

@Motorka A new version in testing, many changes, but the main one you are probably interested in is the option to change to metric.

Other things added: Option to set stove efficiency, better mobile menu few small layout fixes.

Give er a shot and let me know what you think

Third Piece Length (m) change to Woodpile width ?

 

[Nord]

Third Piece Length (m) change to Woodpile width ?

Changed, also added option for that field to be cm or m.

Been awhile!

There have been a ton of changes and improvements to the calculator. Here are some of the big improvements:

- Supports mixed wood stacks, up to four types of wood.

- The data that it uses has changed. I have found that available data for a wide variety of wood types is pretty inconsistent and in many cases sources are not given. So I have attempted to provide some standardization on how figures like BTU and weight are arrived at. It was a pretty big project but I think it has turned out well. You can read about it here: https://boisafeudunord.com/blog/how-i-built-my-firewood-btu-ratings/

- Better handling of field inputs and supports for decimal places.

Pretty big update today, here is what has been done and is now live:

- Improved wood type grouping and changed naming. Now all "Oak" or "Birch" for example are grouped together.
- Added "group" to all "tree_species" in API data for greater flexibility.
- Added some Eucalyptus wood types commonly used in Australia as firewood for our friends down under.
- Wood type dropdown is now more intuitive, selection boxes have been added to clearly indicate a wood type has been selected.
- Search function added to Wood Types selection.
- Bug fixed where absolute 100% was required in wood selection % fields, maing it impossible to select three wood types and calculate.
- Woodpile width default unit changed from in to ft.
- Made text under wood type selection dynamic reflecting what the user has selected or not selected. Changed color for better visibility.
- Wood type % percentage fields now auto-fill based on amount of wood types selected. 1 = 100%, 2 = 50% and so on. These are still editible by the user, auto-fill just streamlines things and makes a bit more intuitive.
- Email: You can now have calculator output emailed to you (your email is not stored).

I have delivered firewood for 20 years or more. A precise firewood calculator like Nord is trying to build is likely an impossible mission. There are too many variables. What I usually hear after I deliver and stack split hardwoods is usually what the customer asks: "How on earth did you get that much firewood packed into your truck?"

That is really all I need to hear to make my delivery successful. Just MHO.
