Fermi in particular has the following syntax

```

5M 12M # number of people living in Chicago

beta 1 200 # fraction of people that have a piano

30 180 # minutes it takes to tune a piano, including travel time

/ 48 52 # weeks a year that piano tuners work for

/ 5 6 # days a week in which piano tuners work

/ 6 8 # hours a day in which piano tuners work

/ 60 # minutes to an hour

```

multiplication is implied as the default operation, fits are lognormal.

Here is a thread with some fun fermi estimates made with that tool: e.g., number of calories NK gets from Russia: https://x.com/NunoSempere/status/1857135650404966456

900K 1.5M # tonnes of rice per year NK gets from Russia

* 1K # kg in a tone

* 1.2K 1.4K # calories per kg of rice

/ 1.9K 2.5K # daily caloric intake

/ 25M 28M # population of NK

/ 365 # years of food this buys

/ 1% # as a percentage

Oh, this is very similar to what I have with Precel, less syntax. Thanks for sharing!
