什麼是容積單位換算器?
What is the Volume Unit Converter?
容積單位換算器是一款專為日常生活與專業用途設計的工具,讓您能即時在公制與英制的體積單位之間快速轉換,無需查表或人工計算。
The Volume Unit Converter is designed for both everyday and professional use. It allows you to instantly convert between metric and imperial volume units without the need for lookup tables or manual calculations.
常見料理容量對照表
Cooking Measurement Reference
做菜、烘焙看到「1 杯」「2 大匙」時最需要的對照,以毫升(mL)為共同基準:
| 單位 Unit | 毫升 mL | 備註 |
|---|---|---|
| 1 茶匙 tsp(小匙) | 5 | — |
| 1 湯匙 tbsp(大匙) | 15 | = 3 茶匙 |
| 1 美制量杯 US cup | ≈ 237 | 營養標示常以 240 計 |
| 1 台灣電鍋量米杯 | 180 | 與日式「一合」相同 |
| 1 罐鋁罐飲料 | 330~355 | 常見易開罐容量 |
| 1 美制加侖 gallon | ≈ 3,785 | ≈ 3.785 公升 |
⚠️ 最常見的錯誤:美式食譜的「1 cup」約 240 mL,但台灣電鍋附的量米杯只有 180 mL。用量米杯去量美式食譜的「杯」,份量會少約四分之一,烘焙時尤其容易失敗——照食譜時請確認是哪一種「杯」。
A frequent mistake: a US recipe "cup" is ~240 mL, but the rice cup that comes with Taiwanese rice cookers is only 180 mL. Using the rice cup for a US recipe under-measures by about a quarter — a common cause of baking failures.
常見問題
Frequently Asked Questions
1 加侖等於幾公升?
1 美制加侖(US gallon)≈ 3.7854 公升(L)。加侖常見於美國汽車油箱規格(如「20 gallons」)、大型飲料容器,以及農業用水量計算。換算時請確認是美制加侖(約 3.785 L)還是英制加侖(約 4.546 L),本工具採用美制加侖。
1 US gallon ≈ 3.7854 liters. Gallons appear in US car fuel tank specs (e.g., "20-gallon tank"), large drink containers, and agricultural water calculations. Note: US gallon (≈3.785 L) differs from Imperial gallon (≈4.546 L) — this tool uses the US gallon.
食譜中的杯(cup)和夸脫如何換算?
標準美制量杯:1 杯(cup)= 約 236.6 毫升,1 夸脫(quart)= 4 杯 = 約 946.4 毫升。本工具支援夸脫直接換算,若食譜標示夸脫,在夸脫欄輸入即可看到毫升或公升等效值。
1 US cup ≈ 236.6 mL, 1 US quart = 4 cups ≈ 946.4 mL. Enter quarts directly in the quart field to see the milliliter or liter equivalents — useful for scaling international recipes.
立方公尺和公升的關係是什麼?
1 立方公尺(m³)= 1,000 公升(L)= 1,000,000 毫升(mL)。這個關係常用於水箱容量計算(如家用水塔)、游泳池體積估算、建築混凝土用量計算等工程領域。
1 cubic meter (m³) = 1,000 liters = 1,000,000 milliliters. This relationship is frequently used in engineering contexts like water tank capacity, swimming pool volume estimation, and concrete calculations in construction.
烹飪中毫升和茶匙、湯匙的換算?
標準換算:1 茶匙(tsp)≈ 5 毫升,1 湯匙(tbsp)= 3 茶匙 ≈ 15 毫升。本工具目前未納入茶匙和湯匙,但可透過毫升欄位輔助:輸入 15 毫升即可換算至其他單位,再自行對應到湯匙量。
Standard: 1 teaspoon ≈ 5 mL, 1 tablespoon = 3 tsp ≈ 15 mL. While the tool doesn't include teaspoons directly, you can enter 5 or 15 mL in the milliliters field to cross-reference with other unit formats.
立方英吋和立方英尺用在哪裡?
立方英吋(in³)常見於汽車引擎排氣量(如 300 cubic inch engine)、電子零件規格;立方英尺(ft³)常用於冰箱容量標示(如「18 cu ft」冰箱)、貨運箱體積計算。在美國文件或商品規格中特別常見。
Cubic inches (in³) appear in car engine displacement specs and component sizing; cubic feet (ft³) are used for refrigerator capacity (e.g., "18 cu ft") and freight volume. Both are common in US product specs and documents.
精確度足夠用於科學實驗嗎?
本工具換算結果精確到小數點後 6 位,採用精確的換算係數(如 1 立方英吋 = 16.387064 毫升)。對於一般實驗室量測已足夠,但高精度分析化學或製藥研究建議使用專業科學計算軟體。
Results are shown to 6 decimal places using exact conversion factors (e.g., 1 in³ = 16.387064 mL). Sufficient for general lab measurements; for ultra-high-precision analytical or pharmaceutical work, specialized scientific software is recommended.

Summary
料理記住 1 茶匙 5 mL、1 湯匙 15 mL 就很好用,但「杯」要小心:美式 cup 約 240 mL、台灣量米杯只有 180 mL。加侖也分美制(3.785 L)與英制(4.546 L),本工具用美制。需要精確換算時,任一欄輸入數字即可。
For cooking, remember 1 tsp = 5 mL and 1 tbsp = 15 mL — but watch the "cup" (US ≈240 mL vs Taiwan rice cup 180 mL) and the gallon (US 3.785 L vs Imperial 4.546 L; this tool uses US).
