It depends on time of day for the most part for me. I easily need 3 times as much insulin for the same amount of carbs (and even the exact same food) in the morning than I do in the evening.
First meal is about 1 unit for 1 gram of carbs, plus a possible dose for 'Foot on the floor' when my liver dumps glucose in my bloodstream to help get me going for the day.
As a late night snack I can easily have 10 grams of slow acting carbs without dosing for it without a discernible difference to my overnight numbers.

Things vary with time of month and of course activity level, and possibly depend on the colour of my socks as well.
 
Hi
I am an old dinosaur.
When i was diagnozed in the 1970s i was put on a "line" diet.
10g of carbs being 1 line.
It was 3 lines for breakfast 4 lines for lunch and 4 lines for tea.(i'm from up north where we have us tea at 6pm).

I still follow the 10g for 1 unit principle but i tweak it for exercise (less) and weekend (more) but there are too many variables for me to concern myself over.

Good luck

Tony
 
As you say - its individual to each of us. I have 1 unit per 8g set - but am using 'Dynamic ISF' so the insulin sensitivity alters based on the last 7 days of use. That means the actual amount used to drop each mmol alters based on what has been happening. I don't bolus for carbs (my loop doesn't need to know what I eat).

Have a look at the bottom graph - the Sensitivity is the light blue wavy line which varies quite a bit during the day.

Using a Dana-i on a DIY FCL (AndroidAPS - Boost version) so no need to enter carbs. Only time I enter anything is for extended bolus (pizza etc) when I tend to go 50% immediate, and 50% over 4 hours - otherwise the 'weak point' (me) has been take out of the over-bolus loop :)
 
Its DIY and not off the shelf (it will be heading to commercial systems but no idea how long that will take).

Nothing is perfect - but makes life easier - I don't count carbs, just eat and it sorts out the food hitting my BG....but large amounts of carbs will send you above 10mmol (as the CGM takes time to register, and even ultrafast takes time to kick in) so if you've eaten a big meal - and then want 'more' sometimes you have to wait for the loop to start reducing the blood sugar.

There are a few systems out there (I use AAPS and Tim Streets variant of that called Boost) - AAPs is a very advanced DIY HCL, Boost adds functionality to 'boost' the insulin amounts based on the size and rate the BG is rising (also does some nice stuff like monitor step count and reduce basal if you're exercising and a load of other bits too).

It takes a long time to get set up - took me a year or so to learn what I needed for a 'fire-and-forget' solution, but I wouldn't go back as its very reliable and has changed how and what I eat (did you know Orange juice is a food to be enjoyed instead of a hypo treatment? - No me either....)

My TIR is 93% TTIR is 73% - I do need to modify some settings to improve this though - I like to run at 96%+ but with a FCL you have to expect some higher than 10mmol time as its always working in the past (CGM time, insulin action time), but should stay below 12mmol if you have it configured correctly.
