Seed germination rate calculator

Test a seed batch and read its viability: the germination rate is simply the seeds that sprouted divided by the seeds sown, as a percentage. Enter both and, optionally, how many seedlings you actually need — it works out how many seeds to sow with a safety buffer.

Teleportation error rate calculatorA gloriously unscientific thought experiment: if teleporters existed, how likely is a botched reassembly? From your body mass, the teleporter tier, the distance and your last meal, it estimates an error rate, your survival odds and the number of atoms it politely misplaces along the way.Vampire apocalypse calculatorA tongue-in-cheek epidemic model: seed a town with a few vampires and it runs a day-by-day predator–prey simulation — vampires feed and convert humans, while slayers and sunlight thin their ranks. It reports how many humans and vampires remain, and the day humanity falls, if it does.Popcorn fill room calculatorA gloriously pointless question, answered with real physics: how many pieces of popcorn would it take to fill a room? From the dimensions and a kernel type it accounts for the air gaps between pieces (~64% packing) and returns the count, weight, cost and a few absurd comparisons.Closet capsule outfit calculatorA small mix-and-match wardrobe makes a surprising number of outfits.

Enter Seeds sown, Seeds germinated, Target seedlings (optional), Safety buffer (%) and the Seed germination rate calculator works out Germination rate, Seeds to sow for target straight away.

How to use it

  1. Enter your values: Seeds sown, Seeds germinated, Target seedlings (optional), Safety buffer (%).
  2. Read the result instantly: Germination rate, Seeds to sow for target.

Frequently asked questions

What does the Seed germination rate calculator actually compute?

It takes Seeds sown, Seeds germinated, Target seedlings (optional) and Safety buffer (%) and derives Germination rate and Seeds to sow for target from them. The calculation is live as you type, so the result updates on every change.

What information do I need to provide?

4 values: Seeds sown, Seeds germinated, Target seedlings (optional) and Safety buffer (%). Nothing else is required — no account, no file upload.

When would I actually use this?

The questions no reference answers: what a meeting is costing while it runs, how many hours a commute has taken out of a year, how much detergent a load actually needs, and a few that exist for the pleasure of knowing — how many popcorn kernels would fill a room, what a hamster generates.

What is the most common mistake?

Quoting the playful ones as if they were measurements. A room filled with popcorn and a salary counted in bathroom breaks are arithmetic done honestly on premises chosen for fun; the number that comes out is exactly as solid as the assumption you fed it, which is the joke.

How accurate is it, and what are the limits?

Germination rate = germinated ÷ sown × 100.

What is the difference between the Seed germination rate calculator and the Teleportation error rate calculator?

This one returns Germination rate and Seeds to sow for target; the Teleportation error rate calculator returns Reassembly error rate and Survival probability. That is the whole difference — open the one whose figure you need.

Where do the figures come from, and how current are they?

The household ones follow the figure printed on the packet or the manufacturer's chart, which is why a detergent dose or a nappy size may not match another brand's. The rest state their assumptions on the page, because assumptions are the whole content of the answer.

GuideNappy Sizes Overlap, and the Smaller One Usually WinsAt 7.5 kg a baby is inside both the size 2 and the size 3 band. Take the 2: a snugger fit leaks less. The step to watch for is the weight at which the smaller band ends, and at 7.5 kg that is eight and a half months away.ExplainerDew Point: What It Is, and How the Calculator Gets ItMagnus–Tetens with the Alduchov–Eskridge coefficients, 17.625 and 243.04.
