Tonnes per Day to Kilograms per Second (t/day to kg/s)
1 tonne per day (t/day) = 0.01157407407 kilograms per second (kg/s). 1 kg/s = 86.4 t/day. Example: 15 t/day = 15 × 0.01157407407 = 0.1736111111 kg/s.

How to Convert Tonne per Day to Kilogram per Second
- 1 t/day = 0.01157407407 kg/s
- 1 kg/s = 86.4 t/day
- Example: convert 15 t/day to kg/s: 15 t/day = 15 × 0.01157407407 kg/s = 0.1736111111 kg/s
Formula
kg/s = t/day × 0.01157407407407
or kg/s = t/day ÷ 86.4
Derivation from SI units:
- 1 t/day = 1000/86,400 kg/s.
- Mass per unit time: kg/s.
Both units are defined exactly, so the factor is exact. Tonne per Day definition: tonne per day; Kilogram per Second definition: kilogram per second.
Worked examples
- A reading of 100 t/day converts to 1.157407407 kg/s.
100 t/day × 0.01157407407 = 1.157407407 kg/s - A value of 1000 t/day is 11.57407407 kg/s.
1000 t/day × 0.01157407407 = 11.57407407 kg/s

Frequently asked questions
How many kilograms per second are in 1 tonne per day?
1 t/day = 0.01157407407 kg/s.
How do I convert tonnes per day to kilograms per second?
Multiply the value in t/day by 0.01157407407, or divide it by 86.4. For example, 15 t/day × 0.01157407407 = 0.1736111111 kg/s.
Is the t/day to kg/s conversion exact?
Yes. Both units are defined exactly, so the ratio is exact; its decimal form does not terminate and is shown here to 10 significant figures (more with the precision selector).
