A calculator that can deal with distributions ergonomically, to allow users to easily arrive at fermi estimates that incorporate uncertainty.
Tips:
■ The boxes represent the 90% confidence interval (5% to 95%) of your distributions
■ Swipe left or right to duplicate an input
Try this example estimating the number of grams lost with a month of exercise lifting:
10 to 30 kg lifted per exercise
× 0.25 to 0.75 meters lifted per exercise
× 9.81 gravitational constant, to get to Jules (swipe left at the bottom to duplicate the input)
× 10 reps per set
× 3 to 4 sets per exercise
÷ 15% 35%, wild guess on chemical to physical efficiency conversion
÷ 4, jules to calories
÷ 6K to 8K, calories burnt to lose one gram of fat
× 7 to 15 exercises in a gym session
× 2 to 4 times a week
× 4 weeks a month
÷ 10% to 30%, wild guess for share of loss that is due to the direct physical exercise
(as opposed to higher burn rate, cost of building muscles, etc.)
= ¿ to ? grams lost with the above exercise regime in a month

force portrait mode, duplicate left input automatically; wipe inputs more often
Duplicating left input automatically might save people a
couple of clicks when operating with scalars. If instead of
clicking "=" the user clicks the right field, the field resets
to zero so that the user can type normally.
Additionally, inputs are now wiped to 0.0 when clicking their respective fields,
rather than having to wait for a "clear" button. This makes the clear button redundant, and so is removed.
