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+21 Femtogram (fg).
| Metric Ton (t) | Femtogram (fg) |
|---|---|
| 0.1 | 1.000000e+20 |
| 0.5 | 5.000000e+20 |
| 1 | 1.000000e+21 |
| 2 | 2.000000e+21 |
| 5 | 5.000000e+21 |
| 10 | 1.000000e+22 |
| 25 | 2.500000e+22 |
| 50 | 5.000000e+22 |
| 100 | 1.000000e+23 |

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 femtogram is a unit of mass equal to 10⁻¹⁵ grams or 10⁻¹⁸ kilograms — one quadrillionth of a gram.
1 fg = 10⁻¹⁵ g = 10⁻¹⁸ kg = 1,000 ag.
To convert fg to kg: multiply by 10⁻¹⁸. To convert fg to pg: divide by 1,000.
Expressing the mass of individual bacterial cells (~100 fg for E. coli) and subcellular components.
A single E. coli bacterium has a mass of about 600–700 fg. A single mitochondrion is roughly 1 fg.
Mixing up fg (femtogram) with fm (femtometer) — one is mass, the other is length.
A bacterium weighs ~500 fg — this gives you a tangible anchor for the femtogram scale.
