Being able to adjust Fahrenheit to a tenth of a Degree

robert.c.brown15

Hello All,

I am curious if being able to adjust the temperature of a sous vide circulator (and therefore waterbath) by tenths of degrees in Fahrenheit is something worth having/useful in a sous vide circulator. I'm interested in the Anova circulator but that option isn't available with it.

The reason I am asking specifically about Fahrenheit is that, besides living in the USA, I have a thermapen that I use and I have set to Fahrenheit. I obviously could switch the thermapen back and forth between Celsius and Fahrenheit when cooking sous vide, but I'd prefer to not have to bother with that and just keep it in Fahrenheit as I use it for many other things besides sous vide. A lot of the sous vide recipes that use Celsius equate to an equivalent Fahrenheit temperature that isn't a round number. I know I could always round, but just based on the various sous vide eggs and how 1 degree can make a such a difference, I wanted to check with you all.

This is might be a strange question but I thought there would be no better place to ask it then here.

Thank you for your help and opinions!

Run the ANOVA in °C and post a °C/°F conversion chart where it's handy.

You could also do a mental calculation. : )

Multiply the °C number by 2, subtract a tenth of that, and add 32.

I'm not really into math. That isn't that hard though.

I guess I could find a chart or something, but it would be nice if the circulator could heat to a tenth of a degree in fahrenheit. Any other opinions. From a cooking standpoint, is having the option of heating to tenths of degrees in Fahrenheit desirable?

lol, you guys know that meme "First World Problems"? This is probably the start of the chefsteps version of that.

Not to be pedantic @DiggingDogFarm but °C to °F is *9/5 add 32.

Source, years of working in Artillery where the thermometers issued read °C and the computer system required °F input. I could bore you with the calculations that charge (propellant) temp has on the range of projectile, but then I would have to explain the Bernoulli principle, rotation of the earth, diff alt and other exciting stuff that puts nerds to sleep.

Converting 20° C to F:

9/5 °C +32

9/5 =1.8

1.8x20=36

36+32 = 68°

As I showed above, which is easier many folks to do mentally:

20x2=40

40-10%=36

36+32=68°

@SamuelG, isn't most of this forum in existence because people are having "first world problems" and require assistance?

I'm curious if needing to calibrate a waterbath to tenths of degrees Fahrenheit is necessary for sous vide cooking. Would rounding off create any issues? Is there a rule to rounding off numbers?

Honestly, if you are going to be cooking SV frequently, stick with Celsius for everything and convert to F when needed, it will make life a lot easier. A quick conversion can be made in google.

Samuel_68313

Yeah of course, I'm just ribbing you.

robert.c.brown15

All good. Thanks for the info. I'll probably just stick with celsius then and do the conversions. I'm practicing the mental math in my head now!

Tim_Sutherland_52834

@DiggingDogFarm, using your formula works but you have to learn a new one to convert °F to °C, unless you are good at 1.11111 multiplication. Transposing mine is °F-32*5/9=°C

DiggingDogFarm_65362

Yeah, it works nicely! : )

@Henri thanks for the vid. I had heard of duodecimal before but first time I have seen this vid.

@Henri - pretty interesting.

I don't think 1/10th of a degree accuracy is all that relevant.
