How Much Canister Gas Produce 1 Need?

Sometimes I encounter people bringing a lot to a greater extent than gas for their canister stove than they actually need.  Now, it never hurts to hold out prepared, but really? Influenza A virus subtype H5N1 450g canister for a uncomplicated weekend trip?  That's potentially a lot of extra weight to pack upwardly a mountain.  Of course of didactics nosotros don't desire to run out of gas, but let's encounter if nosotros can't create a picayune fleck amend inwards price of coming upwardly amongst an justice of the gas nosotros powerfulness need.

The 3 touchstone threaded backpacking canister sizes:
(L to R) 450g, 220g, as well as 110g.  Note:  Some brands vary every bit to exact amount of gas.

Now, before I laissez passer you lot my estimates, allow me country that my estimates are based on my sense as well as my fashion of stove use.  You are your ain best estimator.  If you're somewhat novel to backpacking, hence I'd country err on the side of caution as well as assume that you'll hold out doing "complex" cooking as well as select fuel based on that column from the tabular array below.

What most White Gas?
What's that you lot say?  You don't piece of job canister gas; you lot piece of job white gas?  Ah.  No worries.  Check out How Much White Gas Do I Need?

Making Your Own Estimates
As for your ain justice based on your cooking style/stove piece of job style, commencement you lot ask to larn a gram scale. Then weigh your gas canister before your trip.  On every trip, drib dead on rail of how many meals you lot cooked as well as what type of cooking was involved.  After your trip, weigh the canister again.  The departure betwixt the starting weight as well as the ending weight is the amount of gas you lot used.  If you've kept rail of how much as well as what type of cooking you've done, you lot should hold out able to start estimating your gas usage afterward a few trips.

Estimates inwards the Field
You tin also construct a fossil oil justice of how much fuel you're using piece you're out on a trip.  See my article inwards Seattle Backpacker's Magazine, How Much Gas Do I Have Left?

Using Less Fuel 
Whatever you lot create amongst a stove, drib dead on efficiency inwards mind.  There are basic things you lot tin create to piece of job less fuel piece you're cooking.  I commend to you lot my before weblog post, Canister Gas Stoves -- Recommendations as well as Efficiency.

My Estimates 
OK, similar a shot hither are my estimates.  Note that when I boil water, the H2O is commonly or hence 40F/5C to 50F/10C inwards temperature.  Significantly warmer or colder H2O may crusade you lot to piece of job to a greater extent than or less gas.  If you're melting snow, you lot should roughly double the below estimates.

		For a solo trip
	Jetboil	Conventional Canister Gas Stove (simple cooking)	Conventional Canister Gas Stove (more complex cooking)
Grams per day	15	20	30
		For two
Grams per day	23	30	45

Now, notice 2 things:
1.  For a uncomplicated weekend trip, for ane person, there's no ask to e'er select a 450g canister.  A 110g canister should create nicely unless you're doing a lot of extra heating for drinks, dish water, bathroom water, etc.   Influenza A virus subtype H5N1 reasonably conservative somebody shouldn't ask to a greater extent than than ane small-scale canister of gas for a weekend.
2.  I create non double my estimates if a instant somebody comes.  It's usually to a greater extent than efficient to boil to a greater extent than H2O at a time.  In other words, if you're going to boil a liter of water, create it all at once.  Don't boil 500 ml, empty the pot, as well as hence boil the instant 500 ml.  I'm assuming hither that you lot brought a pot large plenty for 2 people.  If not, hence you lot may ask to allow for higher gas usage.

Remember that my estimates are only that, estimates.  Always banking concern tally that your sense is similar to mine before relying likewise heavily on my estimates.  Particularly inwards really mutual depression temperature or really windy conditions, gas usage may growth significantly.

I promise you lot notice this post service helpful,

Notes as well as Assumptions
1.  The figures higher upwardly assume most half dozen cups (approx. 1.5L) boiled per twenty-four hours for uncomplicated cooking.
2.  Water temperature is assumed to hold out or hence 40F/5C to 50F/10C.
3.  The figures inwards the tabular array higher upwardly create non include snowfall melting.
4.  The figures higher upwardly assume you lot know how to operate a gas stove reasonably efficiently (turn it down!  Running on high wastes gas.) as well as that you've taken measures to shield the stove from wind.
5.  The figures higher upwardly also assume that you lot stimulate got a pot that is broad plenty to grab the flame.  Users of tall, skinny pots amongst a conventional gas stove volition to a greater extent than ofttimes than non piece of job to a greater extent than gas.
6.  Air pressure level is assumed to hold out approx. 900 mBar, the air pressure level commonly institute at most 3000'/900m inwards elevation.  Stove piece of job at lower elevations may require to a greater extent than gas.  Stove piece of job at higher elevations may require less gas.
