ConvertProf has just expanded with four brand-new conversion categories — Cooking, Running Pace, Energy & Power, and Historical Units. Whether you're scaling a recipe, planning a marathon split, comparing engine power, or decoding an old Russian land deed, these new tools turn obscure conversions into instant answers. Below we walk through each category, the most useful unit pairs, and the dedicated landing pages we built for them.

1. Cooking & Kitchen Conversions

Recipes travel across borders, but units rarely follow. American cookbooks measure in cups and tablespoons; European ones use grams and milliliters. Our new Cooking converter handles cups, tablespoons, teaspoons, milliliters and liters in one place.

For the most-searched recipe questions we built focused landing pages with quick reference tables:

2. Running Pace Converter

Runners constantly switch between two mental models: min/km (how long a kilometer takes) and km/h (how fast you're moving). The two aren't linearly related, which is why a dedicated tool helps. The new Pace converter handles every common combination.

What is a good running pace? For recreational runners, 6:00–7:00 min/km (8.5–10 km/h) is a comfortable conversational pace. Sub-elite marathoners hold around 3:00 min/km (20 km/h) for over two hours — a useful benchmark when you're planning training zones.

3. Energy & Power

Energy and power show up everywhere — nutrition labels, physics homework, car spec sheets, electricity bills. ConvertProf now covers both with two dedicated categories.

Use the Energy converter for joules, kilojoules, calories and kilocalories, and the Power converter for watts, kilowatts and mechanical horsepower. Highlights:

  • Calories to Joules — 1 cal = 4.184 J. The bridge between nutrition and physics.
  • Kcal to kJ — every EU food label requires both. 1 kcal = 4.184 kJ.
  • kW to HP — modern EVs are rated in kW; legacy ICE specs in HP. 1 kW ≈ 1.341 HP.
  • HP to kW — useful for European registration paperwork on US/Japanese cars.

4. Historical Units (Our Unique SEO Differentiator)

Most converters stop at metric and imperial. ConvertProf goes further with historical units — the measurements you encounter in old documents, novels, genealogy research, and museum exhibits. All values are clearly marked as approximate, since regional variants differed slightly across centuries.

  • Pood to Kg — the Russian Imperial mass unit. 1 pood ≈ 16.38 kg. Common in 18th–19th century trade records.
  • Verst to Kilometers — the classic Russian distance from Tolstoy and Dostoevsky. 1 verst ≈ 1.0668 km.
  • Cubit to Centimeters — the ancient forearm-length unit used in the Bible, Egypt and Mesopotamia. 1 cubit ≈ 45.72 cm.
  • Desyatina to Hectares — the Russian land area unit critical for reading pre-1917 property deeds. 1 desyatina ≈ 1.0925 ha.

These pages exist because almost no one builds them, yet historians, translators, genealogists and literature students search for them every day. If you've ever stumbled on "verst" in War and Peace or "cubit" in an architecture textbook, this is the answer.

Why we built dedicated landing pages

Every conversion in this article has its own URL — short, memorable, and shareable (e.g. /cups-to-grams or /kw-to-hp). Each page includes the live converter, a quick reference table, and contextual links to related conversions. The result: faster loading, better mobile UX, and search results that take you straight to the answer instead of a generic homepage.

What's next

Currency conversion with live exchange rates, a programmer's calculator (binary, hex, octal), and BMI / health calculators are on the roadmap. If a unit you need isn't covered, let us know — niche requests often become our most-loved pages.
