Ton (short, US)

What is a ton (short, us)?

The short (US) ton equals 2,000 pounds, about 907 kilograms.

Origin of the ton (short, us)

The American ton, equal to 20 short hundredweight.

Where it is used

US industry, mining, and commodity output.

When and where it was developed

Standardized within US customary units.

Carat (metric) to Ton (short, US) conversion formula

The relationship between carats (metric) and tons (short, us):

1 ct = 2.204623e-7 sh tn
1 sh tn = 4535923.7000000002 ct

To convert carats (metric) to tons (short, us), multiply the value in carats (metric) by 2.204623e-7. To reverse, multiply tons (short, us) by 4535923.7000000002.

How to use this converter

Type a value into the calculator. The result in tons (short, us) updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Ton (short, US) to Carat (metric) converter for the reverse direction.

Step-by-step: convert carats (metric) to tons (short, us)

  1. Write down the value in carats (metric) (ct).
  2. Multiply that value by the factor 2.204623e-7.
  3. The product is the equivalent value in tons (short, us) (sh tn).
  4. To reverse, multiply the ton (short, us) value by 4535923.7000000002.

Worked examples

Example 1 — Convert 1 ct to sh tn:
1 × 2.204623e-7 = 2.204623e-7 sh tn

Example 2 — Convert 100 ct to sh tn:
100 × 2.204623e-7 = 2.204623e-5 sh tn

Real-world example — Paper and film thicknesses

At the thickness of office paper (roughly 3 carats (metric)), converting between sub-millimeter units is routine for packaging and printing buyers comparing quotes from metric and US suppliers.

3 ct × 2.204623e-7 = 6.613868e-7 sh tn

Real-world example — Plastic-film thickness alternates

A 150-carat (metric) plastic film converts cleanly to tons (short, us) — useful for packaging buyers reconciling supplier datasheets across metric and US measurement systems.

150 ct × 2.204623e-7 = 3.306934e-5 sh tn

Real-world example — Hair-width scale measurements

A 70-carat (metric) measurement (about the diameter of a human hair) is the kind of value materials engineers regularly express in adjacent micro-scale units like tons (short, us) for direct comparison across supplier datasheets.

70 ct × 2.204623e-7 = 1.543236e-5 sh tn
