Day 8: Recipe Conversions Without the Panic (Unit Converter)

It’s Day 8 of 12 Days of Svelte Apps 🎄

Holiday cooking is fun… right up until the recipe switches units on you.

• cups vs milliliters
• ounces vs grams
• Fahrenheit vs Celsius

So today’s mini-app is the Unit Converter — a clean, fast converter you can keep open while you cook.

What it does

The UI is intentionally simple:

1. Pick a unit category (Volume, Temperature, Mass, etc.)
2. Enter a value
3. Choose “From” and “To” units
4. Get a formatted result instantly

It also includes a Swap button so you can flip the direction quickly, and a Clear action to reset the input.

What makes it feel good to use

• Results are formatted cleanly (so you don’t get unreadable long decimals)
• It handles "same unit" conversions gracefully
• It supports a wide set of categories beyond cooking too (length, area, time, angle, data, energy, force, power, pressure)

A few holiday-friendly conversions to try

Oven temperature

If your recipe says 350°F but you’re using a °C oven, pick Temperature and convert.

Cups to milliliters

For recipes written in US cups, pick Volume and convert to mL for a measuring jug.

Ounces to grams

For baking (where precision matters), converting to grams can make measuring a lot easier.

If you try it, post a conversion you used today (or a recipe you’re making) and tag me.
