© Measurements Calculator — Conversion factor: 1 oz = 28.349523125 g (NIST, exact)

Below you’ll find every way to express 495 grams in imperial weight units — from ounces and pounds to grains and carats. In short: 495 grams equals 17.46 ounces, or 15.9146 troy ounces if you’re weighing precious metals. The calculator above handles both ounce types and reverses the conversion at the press of a button.

Because the gram-to-ounce relationship is fixed by international agreement, the answer to “how many ounces is 495 grams?” never changes with the ingredient — unlike volume conversions. The exact factor (1 oz = 28.349523125 g) was set by the 1959 International Yard and Pound Agreement and is maintained by NIST.

How to Convert 495 Grams to Ounces

Step 1: Use the Exact Conversion Factor

Both grams and ounces measure mass (not volume), so there’s no density to look up — the conversion is a single, fixed multiplication. The internationally defined relationship is:

1 ounce = 28.349523125 grams  |  1 gram = 0.03527396195 ounces

Step 2: Apply the Formula to 495 Grams

To turn 495 grams into ounces, divide by the grams-per-ounce factor (or, equivalently, multiply by 0.03527396195):

Ounces = 495 ÷ 28.349523125 = 17.4606 oz

Quick mental math: Dividing by 28.35 is a hassle in your head. A useful trick: divide grams by 28 for a fast estimate, then add about 1.2 %. For 495 g that gives roughly 17.46 oz — close to the exact answer.

Step 3: Worked Reverse Example

Goal: Confirm 17.46 ounces converts back to 495 grams.

1. Use the reverse formula:

Grams = ounces × 28.349523125

2. Plug in 17.46 oz:

17.46 × 28.349523125 ≈ 495 g

Small rounding differences appear because the displayed ounce value is truncated to two decimals — the calculator above uses the full-precision factor and will round-trip exactly.

Step 4: Decide Which Ounce You Need

Not every “ounce” is the same unit. Match the ounce to the situation:

  • Standard ounce (28.349523125 g) — food, kitchen scales, postage, retail, nutrition labels. Sometimes called the “avoirdupois” ounce in formal references. This is what 495 g = 17.46 oz refers to by default.
  • Troy ounce (31.1034768 g) — gold, silver, platinum, palladium. 495 g = 15.9146 troy oz.
  • Fluid ounce — a volume unit, not a weight. Don’t mix it up with the standard mass ounce.

Rounding rules used on this page: Ounces are displayed to two decimal places for everyday use and four decimals for precision. Troy ounces are shown to four decimals because precious metals trade at fine resolution.

Four hundred ninety-five Grams in Context

Weight class: moderate

495 grams is best described as about moderate weight (~500 g). On a kitchen scale you’ll see a reading of 495 g; on an American postal scale or imperial scale the same item registers as 17.46 oz. That difference is purely the unit you’re reading — the mass itself is identical.

Pocket digital scales often default to ounces. Switch units before weighing rather than converting after — it removes a rounding step.

If you’re working with bullion, the same 495 grams equals 15.9146 troy ounces. A troy ounce is about 9.7 % heavier than a standard ounce, which is why precious-metal weights look smaller in troy-ounce form for the same gram value.

Grams & Ounces — A Quick Primer

The Gram (g) — Metric Mass

A gram is the metric system’s everyday unit of mass, defined as one-thousandth of a kilogram (the SI base unit). It was originally tied to the mass of one cubic centimetre of water at 4 °C. Today, the kilogram — and by extension the gram — is defined through Planck’s constant under the 2019 SI redefinition, making it independent of any physical artifact. Grams are the standard unit on most kitchen scales outside the United States and on every pharmaceutical or scientific scale worldwide. 495 grams is a value commonly seen in moderate-weight contexts.

The Ounce (oz) — More Than One Definition

“Ounce” is one of the most reused words in measurement, so always check which one a recipe, label or price refers to. Three different ounces are still in regular use, and they each give a different answer for 495 grams:

Standard ounce (avoirdupois)

= 28.349523125 g (exact). The default ounce for food, postage, and consumer goods. When a recipe or label says “oz” without qualification, this is the unit. 495 g = 17.46 oz.

Troy ounce

= 31.1034768 g. Used for gold, silver, platinum and palladium. 495 g = 15.9146 oz t.

Apothecaries’ ounce

= 31.1034768 g. Historically used in pharmacy. Equal to the troy ounce; rarely used today.

Fluid ounce (avoid!)

A unit of volume, not mass. US fl oz ≈ 29.57 mL, UK fl oz ≈ 28.41 mL. Never mix it with the mass ounce.

Why the Conversion Is Exact

Unlike grams-to-teaspoons or grams-to-cups (where the answer depends on the ingredient’s density), grams-to-ounces is a fixed mass-to-mass conversion. The 1959 International Yard and Pound Agreement defined the pound as exactly 0.45359237 kg. Sixteen ounces fit in a pound, so one ounce is exactly 28.349523125 grams — and the conversion of 495 grams to ounces is exact to the limits of arithmetic, not an approximation.

FAQ: 495 Grams to Ounces

❓ How many ounces is 495 grams?

495 grams equals 17.46 ounces, or 17.4606 oz at full precision. If you’re weighing precious metals, the same 495 grams is 15.9146 troy ounces.

⚖️ Does the answer change for different ingredients?

No. Both grams and ounces measure mass, so the conversion is fixed regardless of what you’re weighing. 495 grams of feathers and 495 grams of lead are both 17.46 oz — they just take up wildly different amounts of space. (The “different for each ingredient” rule only applies when one side is a volume unit such as teaspoons or cups.)

📏 What’s the exact formula?

Ounces = Grams ÷ 28.349523125  |  Grams = Ounces × 28.349523125
For 495 grams: 495 ÷ 28.349523125 = 17.4606 oz.

🥇 What if my recipe is for gold, silver or another precious metal?

Use the troy ounce instead. The factor is 31.1034768 g per troy ounce, so 495 g = 15.9146 oz t. Bullion bars, coin specifications and gold/silver spot prices are quoted in troy ounces by global convention.

🎯 What’s the most accurate way to measure 495 grams?

A calibrated digital scale that reads in grams. Even an inexpensive pocket scale measures down to 0.1 g, which is more than enough for 495 g. Avoid converting through a volume unit (teaspoons, cups, fl oz) when you actually need a mass — every volume-to-mass step adds error.
Pro tip: If your scale shows ounces only, set it to display two decimal places. 17.46 oz on the scale is the correct reading for 495 g.

🔁 How do I reverse-check this?

Multiply the ounce result back by 28.349523125 and you should recover 495 g (with a small rounding tolerance if you used a truncated ounce value). The calculator at the top of this page does the round-trip at full precision.
