To convert tonnes to kg: multiply by 1,000. To convert tonnes to short tons: multiply by 1.10231.
1 t = 1,000 kg = 10⁶ g = 2,204.62 lb = 1.10231 short tons = 0.98421 long tons.
For example, 1 Metric Ton (t) = 1.000000e+24 Attogram (ag).
| Metric Ton (t) | Attogram (ag) |
|---|---|
| 0.1 | 1.000000e+23 |
| 0.5 | 5.000000e+23 |
| 1 | 1.000000e+24 |
| 2 | 2.000000e+24 |
| 5 | 5.000000e+24 |
| 10 | 1.000000e+25 |
| 25 | 2.500000e+25 |
| 50 | 5.000000e+25 |
| 100 | 1.000000e+26 |

The metric ton (tonne) is a unit of mass equal to 1,000 kilograms or one megagram.
1 t = 1,000 kg = 10⁶ g = 2,204.62 lb = 1.10231 short tons = 0.98421 long tons.
To convert tonnes to kg: multiply by 1,000. To convert tonnes to short tons: multiply by 1.10231.
Cargo shipping, vehicle weight ratings, construction material ordering, and agricultural harvests.
The three 'tons' often cause confusion: metric tonne (1,000 kg), short ton (907 kg, US), and long ton (1,016 kg, UK).
Confusing metric tonnes with short tons (US) or long tons (UK). A metric tonne is 10% heavier than a US short ton.
1 tonne = ~2,200 lb. Quick check: multiply tonnes by 2.2 to get approximate thousands of pounds.
The attogram is a unit of mass equal to 10⁻¹⁸ grams or 10⁻²¹ kilograms — one quintillionth of a gram.
1 ag = 10⁻¹⁸ g = 10⁻²¹ kg. A single HIV virus has a mass of about 10¹⁰ ag.
To convert ag to kg: multiply by 10⁻²¹. To convert kg to ag: multiply by 10²¹.
Measuring masses of individual nanoparticles, viruses, and large biomolecules in nanosensor research.
In 2012, researchers achieved single-proton sensitivity (1.67 × 10⁻⁶ ag) using carbon nanotube resonators.
Confusing atto (10⁻¹⁸) with femto (10⁻¹⁵) — they differ by a factor of 1,000.
Follow the prefix chain down: milli, micro, nano, pico, femto, atto — each step is 1,000× smaller.
